25,4mm = 1 inch. 25,4 × 0,223 = 5,66mm. So a close one but not exact by a difference of 0,1mm. 25,4 × 0,308 = 7,82mm. Again close but with a bigger difference of 0,2mm... oh and 7.62 may be Russian (famous use for ak47), but it's still metric.
@@shadowfox009x Or maybe as a British: "What size of cup?" As many other differences between American and UK measures with the same name (ounces, for one), a cup as measure is ambiguous.
@@shadowfox009x this one always confuses me. A cup could mean liquid or solid, but which is which. At least 250ml of water = 250g. 1000ml = 1 kg. Doesn’t that make more sense, everything revolving around water?
It is kinda ironic that the US fought a war to be independent from the influence and the shackles of a king and yet cling to the imperial measuring system like to an old love you can´t get over.
Well yeah, the whole "muh freedom" is a well known caricature for a reason. They don't exactly keep raving about that "freedom" of theirs for well thought out reasons.
Add to that Irony, the fact that US pints are smaller than UK pints (UK pint = 20oz/568ml - US pint = 16oz/473ml). So they changed some of the Imperial measures, at some point for alternative 'Imperial' measures.
i know that it was measured in egypt, but was that done by greeks? i thought it was the egyptians. they did build the great pyramids in alignment with stars, so they were at least capable of doing it. from what i remember, they measured the shadows of 2 sticks at the same time of day, and due to their no-equal length proved the curvature of earth.
@@agromx224 in fact Eratosthenes was a Greek mathematician and astronomer of the 3rd century BC Jesus Christ (born in -276, died in -194). He lived in Alexandria where, as director for several years from the great library of Alexandria, he had access to practically all the mathematical and scientific literature of his time. He has left some original works, whose measurement, remarkably precise for the time, of the earth's circumference. The measurement of the angle between the stick and the sun's rays should be taken at Alexandria at noon on the day of the summer solstice. This allows the comparison with Syènewhere, the city being on the Tropic of Cancer, the rays of the sun are perfectly vertical at this time. On the geometric model we see the extension of the ray of the sun which, from Syene, goes straight towards the center of the earth. In fact, this was known by Eratosthenes. At noon on the day of the summer solstice, there was no shade at the bottom of a well in Syène, the sun being exactly vertical to the well. Essentially, to measure the earth's circumference, Eratosthenes has used two commonplace things in his time: - a stick planted vertically in Alexandria and whose angle with the rays solar is equal to the angle at the center of the earth between Alexandria and Syene, as the geometric model shows it. - a camel to measure the distance between the two cities. Camels were reputed to have a very even pitch. Several hypotheses exist: perhaps that Eratosthenes simply measured the average distance traveled by a camel in a day and multiplied by the number of days the journey takes, maybe he used a step counter (a bematist, a real profession to the time to measure the distances) in which case the steps measured could have been those of a camel, probably, but perhaps those of a man. 😉
Between Imperial Units, Fahrenheit degrees for temperature, 12 hour time system, writing dates in an order of MM/DD/YY and starting their week on Sunday in calendars, I am by now convinced we are living in different realities 🤣
I thought in the US they start their week on Monday in calendars. In Portugal we start the week on Sunday because Monday is "segunda-feira", literally "second fair" (and tuesday is thrid, wednesday fourth, etc.)
@@RavensBlue Well yeah countries that are still atleast little bit Christian (Or Muslim) use the correct day to start the week (Aka Sunday) Otherwise it's Monday that became the 1st day of the week due to American softpower/Irregelion becoming the majority everywhere (In France ,we were using Sunday as the 1st day before we switched to Monday during the Cold War)
The order of dates is just horrible >.< You order it depending on length ... either the longest first, going down to the shortest (YY/MM/DD) or the shortest first, going up to the longest (DD/MM/YY) ... The month is ALWAYS in the middle ... not doing that makes no sense at all >.
The main problem with Imperial units is, that you have different units for the same task: measuring length for instance. You have inches, feet, yards and miles, each of them arbitrarily defined, and thus you have 12 inches in a foot, but 3 feet in a yard and 1760 yards in a mile. In SI units, there is exactly one unit of length, the meter. Kilometer or Millimeter are no new units, just meters times a power of 10. In imperial units, you have units of area and units of volume, which are not compatible with the units of length. A gallon is not a cubic foot or something easy, but 128 fluid ounces, and 231 cubic inches. While 128 might be somehow understandable (2 to the power of 7), but why 231 cubic inches? 3 times 77 cubic inches? Where does the 77 come from? In SI units, the unit of volume is the cubic meter: 1 meter of length times 1 meter of height times 1 meter of depth. Quick and easy to remember. Imperial units were designed before Isaac Newton discovered the fundamental Laws of Mechanics and the Law of Gravity. Before Isaac Newton, scientists didn't notice that mass is a property of a body, but weight is the force on a body in a gravitational field. Thus, pound was used for both the mass and the weight. Now, we have pound-force, but again, arbitrarily defined as the force a body of a mass of 1 pound experiences in the average gravitational field of the Earth at the Earth's surface. In SI units, the unit of Mass is kilogram, and according to Newtons first law, Force is the acceleration of a mass, thus Force is measured in kilogram times meters per square second, as meters per square second is the unit of acceleration.

Btw.: Even the imperial system is now based on metric. An inch is 2.54 centimeters. Not just about that, but exactly, that's how the inch is defined now. So every change to metric (for example more exact measurements leading to a change in the 10th digit) carry over to imperial automatically. Imperial just rides on top of metric now, for those people who like it a bit more complicated.
I'm from Belgium and as an engineer I'm very familiar with the metric system of course and a bit with the medievel (sorry for the word) system. I cannot understand why it is still used. But in fact, compare it with the European currency: before 2002 every country in Europe had its own currency. Every time you travelled you needed to switch currency and you didn't know exactly how much money you spent. In 2002 we started to use the Euro. In the beginning we had to adapt to this new currency, but after a few years everybody got used to it and now we all know exactly the value of the Euro. If we Europeans can change our money, I'm sure the Americans can also change from imperial to metric. What are you guys waiting for !
What we're waiting for is NOT your approval. Who the hell cares if you adopted the Euro, or a metric system. You're clearly being controlled or influenced by your government, so your take/views mean absolutely nothing to us Americans. The mere fact that you're here shilling for it shows how much of an NPC you truly are.
The euro has nothing to do with this subject, measurements and currency just aren't the same at all. 1 reason to resist the change is that it would be expensive. Every single road sign with miles would become outdated, and they might need road signs with both measurements in the transition period. Every car with a mile meter would also become outdated after the full transition. I'm sure there are tons of other examples of where it will cost for both the government, and the people. It just isn't that simple of a deal, and rarely things are THAT simple when you really look into it.
@@ArcticWolfGod it's an example of change. You say metrication is expensive because all the road signs need the new units. Guess what? When the euro was introduced, all prices in all supermarkets had yo be changed as well as ATM's and cash registers all over the continent. It's the same.
Smart people don´t run for office, Ryan. People who run for office are usually not the brightest canlde on the cake, but the fattest, power-greedy ones.

"They have to be in cahoots with the politicians to pass this kind of stuff?" Actually, in the case of the French Revolution, they mostly killed all the old guard (conservative) politicians, which is how they actually managed to do some progressive and useful things for society despite their initial cost.
"some progressive and useful things" that period is called "the terror". "despite their initial cost." You mean the same cost as always, a pile of dead bodies. Cutting the heads of all the competent people served them well at Trafalgar. And an emperor is much better than a king. Progress.

damn dude you dont know your history very well when you say what you say. Metric system is hella better, thats obvious. But revolution in that shape wasn't good thing at all. Revolution devours its children. Always.
Favorite metric system quote is by Josh Bazell. “In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade-which is 1 percent of the difference between its freezing point and its boiling point. ... Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go f**k yourself,’ because you can’t directly relate any of those quantities.”
4:30 actually there was originally an effort to make time metric, too. A day would have been divided into 10 hours, each hour into 100 minutes and each minute into 100 seconds. The reason this change was rolled back after a very short time was that it would have required to replace all public clocks, which would have been prohibitively expensive. So at the end of the day, the second is a metric units, and the derived units (minute, hour, day, year) continue to be officially authorized derived units, despite not being based on the unit 10.
i disagree with categorizing a second as a metric unit (for now). because it's used by the metric system to define units, it's now a set amount of time and not the 1/86,400th of a day. days are getting ever so slightly longer, so they had to preserve it's value for the integrity of metric system. metric seconds will become a thing once earth's days are longer than 86400 metric seconds long, but for now it's too miniscule to worry about (we struggle to be accurate enough that this would even matter)
@@PyrokineticFire1 the second totally is one of the SI basic units. However, it ceased being defined as the 86,400th part of the day a long time ago, and for the reasons you cited - the "Earth day" not being a universal, unchanging constant. Nowadays the second is defined by the physical properties of a Cesium isotope. The definition would still work even if Earth ceased to exist.
When ever I watch US-american movies or shows, I do crappy math in my head to understand what you guys are talking about. Love you anyways, best wishes from Germany 🌻

@@bochica3562 When i think, that, ironically, some Americans actually refer to the old colonial units as "Freedomheit"...^^ Also in science, medicine and military, the metric units are pretty much standard in the US already and where they are not, they get converted all over the place. Coz in the End, the metric system is much easier and much more accurate and consistent. I mean, look at temperatures, look at lengths, look at mass, look at volume, even time or date, so many different units, measurements and writings, all arbitrary and incoherent and bluntly confusing and annoying af. And yeah the in your head approximating conversions you have to do, is also taking a lot of fun out of stuff and adds an additional layer of brainwork to do, which slow the processing of the relevant information.
mistake! The video said there are only three countries that don't use the metric system, it didn't say that all three use the imperial system. Myanmar uses neither metric nor imperial, it has a traditional system of its own. Liberia would officially continue to use the imperial system since it is a US colony, but the people practically use the metric system. The United States is the only country in the world that still uses Babylonian units of measurement
@@Lo1wirm Not just that, medicine, engenering, so on and so forth might have the imperial system, but it also has if not garantied, bery likely at least, the metric system. I'm just waiting for the new system to be released, since even the metric is based on our planet, but the system should be based on the laws of the universe itself, like the rest of it's parts. I think it's only a matter of time before a new and better system is made, the real question is, before or after space travel becomes mainstream?
@@anubis9151 But the metric is already based on time of the speed of light (which is like a law, it doesn't change). And generally they are based on some way on such laws. Before the idea was to define meters with the planet, but that change.
@@anubis9151 There won't ever be a new system that you will get to use on a day by day basis like the metric system. As you mentioned, it is a human scale. As a human it won't get bigger than that and there are already units in place for intergalactic travel it's just that you have absolutely no reason to ever use a bigger scale as long as you don't work in somewhere in the spacecraft industry. Sure the large units we use like lightyears are susceptible to change as they are derived units but I don't think you ever said that you have a 2,114e-13 lightyears work commute, nor will you ever. Put simply the system already exists and it has nothing to do with either the metric or the imperial system. Also the metric system is legitimately based on the laws of the universe. It is striving for our units to not be defined by human understanding but by hard facts. It's actually very interesting to read into the SI system and their achievemnts within it.

Yeah and the thing is... is wrong... imperial is far from being intuitive. 12 inches is a foot, 3 foot is a yard, i dont know how much is a mile but is around more than 1000 yards thats for sure... you need to fucking remember every single measurement while metric is far simpler 1000 milimeters is one meter or 100 centimeters, 1000 meters is one kilometer, etc 1000 grams is a kilogram, 1000 kilograms is one ton, etc
@@sebasblos1 I get you, I don't know imperial because I'm not from the US, but when I put myself on the shoes of someone who grew up using imperial ofc it makes sense. This is not a "metric is more intuitive" case. This is "what I grew up with and is everywhere around me is more intuitive" situation.
This is the excuse especially for temperatures, of course to them °F feels more human, they've not grown up with °C and made the association that 30° is really hot when to them it means it's cold. To me the connection of the freezing and boiling points of water feels more generally intuitive. The most insuler comment I've heard is that 0°f - 100°f is the bearable range, anything beyond that isn't bearable, which ignores that that is somewhat subjective to an individuals perception rather than a global constant (I'm aware water purity and atmospheric pressure does make a difference between freezing and boiling points of water, which is why Celsius is based on pure water at average sea-level pressures, water will boil at lower temperatures up on mountains, so you'd need a pressurised kettle to make a good cup of tea on mount Everest 😅)
Which is interesting, because the ratio between the length and the width of the sheet is always the square root of 2, however many times you cut the sheet in two equal parts.
You asked about time.... actually the french (under Nepoleon Bonaparte) wanted to change the clock system to metric as well. Meaning, a day has 10 hours, a hour has 100 minutes and a minutes has 100 seconds. But that was too much of a leap for the population, same as the 10 day week. And it also would have meant, that ALL existing clocks would be useless and need to be replaced by new ones. And clocks were expensive back then, so people didn't like the idea at all. And thats why we still have 24 hours, 60 minutes and seconds today.
@@iseeyou3129 Yeah, thats why you would need new clocks. They actually do exist from around 1800, but are pretty rare collectors items. Basically, it doesn't matter how a day is divided, its still a day. It just much easier to calculate when using metric divisions.Its the same as withe weeks and month - a astronomical year stays always the same.
And the sexagesimal system, inherited from Babylon is quite useful as you can evenly divide hours or minutes into 2, 3, 4, 5, 6, 10, 12, 15, 20 or 30 intervals.
Before I see someone comment "But did it win the Space Race?". The answer is Yes, NASA used and still uses the Metric System. The measurements had to be converted to Imperial units for the manufacturing process. Edit: 04:25 - M-K-S... Meter, Kilogram, Second.

The second is measured with cesium, it is based on a certain number of it's vibrations and is very very precise (around 10 decimals), and today's atomic clocks, uses cesium to be precise.
It actually took years to measure the first meter. Since they couldn't measure the whole length from northpole to the equator, they measured from dunkirk to barcelona which is roughly 1/10 of the length. They did it using methods of triangulation and modern Equipment
These were indeed large scientific projects of the day; another one was the triangulation survey of the Struve Geodetic Arc, stretching from the coast of the Arctic Ocean to the Black Sea over 2800 km to the south.
I mean to be fair we had a pretty good estimate of the circumference back in the 3rd century BC. Eratosthenes measurement was a little on the large size with the true value being just bellow the lower bound of his estimate but not by much. His estimate was in the region of 40,250 to 45,900 kilometres, the actual values are 40,008 km polar and 40,075 km equatorial. But still you know this was done with a couple of sticks and a camel to travel between observation points over 2,200 years ago. Over the years this was further refined with more data from more observations but it makes it really depressing that modern humans have trouble figuring out such simple things with advanced computers and the internet etc which ancient people were figuring out with sticks, camels, and an abacus thousands of years ago.
@@Tuboshi0815 Original proposal was to define it on basis of a pendulum. The one that stuck before the prototype metre was formed was specifically "one ten-millionth of the length of a great circle quadrant along the Earth's meridian through Paris", not length along the equator.
During Napoleon's rule the Grand Duchy of Baden in south west Germany became an ally of France. Tulla was an officer and civil engineer in the army of the Grand Duke. The Ecole Polytechnique in Paris was founded as a military academy during the French Revolution and Tulla received permission to stay there for studies for some time. The Ecole Polytechnique enjoyed the reputation as the leading engineering school in the world (it's still very reputable). Returning from Paris Tulla initiated two things: firstly he recommended to the Grand Duke to establish an engineering academy along the principles of the Ecole Polytechnique, the Technical University of Karlsruhe. And secondly he recommended giving up old unit systems in favour of the French system with Meter, Kilogramm, and Second (MKS) which became the Systeme International des poinds et messures (SI). The next to adopt the MKS system was the German Kingdom of Württemberg, east of Baden. After the wars with Napoleon and after the Congress of Vienna, industrialisation was picking up speed in German countries and the advantage of the French metric system was recognized gradually all over Germany.

Details and fun facts: - When the month was divided into three ten-day weeks, only the last day was for rest. This meant only three days off a month (instead of four) after a 9-day working week.... Of course everyone rebelled against this new usage and it was VERY quickly abandoned!!!! - the other idea that didn't work was 10-hour days (still based on 10 mathematics, with 100 minutes)... But that would have meant changing all the clock systems in the whole country... difficult... Especially as a home clock was a luxury in those days, and in France it was church bells that told the time... an idea quickly abandoned too! Nowadays, you can sometimes come across so-called "revolutionary" clocks in antique shops, with two dials (10-hour and 24-hour). These are rare and expensive collectors' items, as few of them were ever produced! From 🇫🇷
Something to not mentioned here is how interlinked all the metric measurements were. You had the Metre which was defined by the circumference of the earth. Then you have the Litre which is 1000cm³. And the Kg which was the weight of 1 litre of water. And the KiloCalorie which is the energy required to raise the temperature of 1 litre of water by 1°C

@Peter de Jong Please note that I was talking about the 1800s and early 1900s. No wars were started in my part of the world at that time. The brutality and insanity of the middle ages came back with socialism! Say in Sovjet, China, Germany (National Socialists), Italy (the fascism led by marxist Mussolini) and so on. Postmodern deconstructivists are still thinking in very marxist terms, so much of that totalitarian mentality remains. I'm optimistic when/if there are reasons for it, not because you say I should be... :D Also, most of the scientific groundwork for our technological achievements during the last 50 years was done before WWII. And the mathematical grounds for it was largely invented and sorted out around the 1700s.
@Peter de Jong Also keep in mind that wars are often an impulse for developing new technologies and ideas. Nothing is a better proof that "Knowledge is Power" than an arm race, in which developing a technology faster than your enemy gives you advantage and can even help you win the war. Like the radar, for example, that allowed the British to detect German airplane bombers approaching before they got close enough to be visible. Or read about all the inventions Archimedes came up with to protect the city of Syracuse sieged by Romans. Wars end, but knowledge remains, and can then help us grow in the times of peace.
@Peter de Jong _"Archimedes is an ancient myth"_ Oh, you are one of _those_ people? ;q What else? Rome didn't exist either? Dude, what are you even talking about. If you made just the basic research (i.e. on Wikipedia), you would find TONS of historical sources documenting Archimedes's life, as well as his involvement in the siege of Syracuse during the Second Punic War, and his inventions that helped protect the city. Not only from Greek sources, but from Roman sources as well. Also I never said that war is good. I just said that despite all its atrocities, it often causes development of science and engineering because "a need is the mother of inventions". During the time of peace, science might thrive too, but there isn't that much pressure on developing it and even less pressure on applying it. Ideas might develop, but they're not necessarily converted to new technologies until there's an actual need to do that. (Like with the radar.) Anyway, I don't think that you're a good partner for me to discuss such things, so let me end on that note.
Portugal was one of the first to adopt metrics, and even to this day, villagers/old people still talk about the old measures that are actually not in use for almost 2 centuries. When they talk about them, they are aware of the equivalent metric unit.
This is true. Some of my grandparents still talk about some of those measures when they talk, although they don't really use them at all. Those ancient measurements are also very present in traditional and old songs as well.
3:45 it was the same when the euro was introduced. For years people were still converting euro to their old currency to get an understanding of how much something cost. Mostly then complained at how higher the prices were. 😂
Yeah, in eastern Germany it became a bit of a meme to convert Euro to D-Mark and then to Ostmark, sometimes with ridiculous rates. "WHAT?! 5€? That's 10 DM; almost 50 Mark Ost! That's 500 Mark Ost on the Black Market!" x'D
Even in a country as small as the Netherlands, people choose to define their own standards - until the ridiculousness enforced change. Like how clocks were not synchronised, which made "I’ll be arriving at noon" a very flexible concept, from one town to another.
In Sweden it took the building of the railroads to get a unified time - putting two trains on the same line because the two ends had different opinions on what the time was, was bad ... For axwhile there were 4 different times one might've had to consider in Sweden; the _local time_ Ömsolar time (based on longitude, differing 45 minutes between Haparanda and Strömstad, 24 minutes between the 2 largest cities of Stockholm and Gothenburg. _Railroad time_, based on Gothenburg time, was chosen for the railroads, and many stations had clocks w/ dual minute hands (local and railroad). _Telegraph time_ I suspect its use in trades required everyone to be able to agree to what time something was sent.@ _Navigation time_ - likely to avoid the need of local tables for things like celestial navigation and tide charts. In 1878 a single time was introduced (based on a compromise, as Stockholm, capital, wouldn't see railroad/Gothenburg time, over Stockholm time - so a compromise somewhere in-between was agreed.
In england we have feet and inches on one side of a tape measure, and metric on other side. We also use pounds and ounces alongside metric weights. You can pick and choose as you like
2:30 It's not so much that people were smarter, or that politicians were. But it's that a Revolution was the perfect context to pass radical changes, without the weight of such an elite class caring more about their place than policies and people. Scientists were simply listened to, because there wasn't a political motivation to not do so. That's also why the most advanced and progressive societies are those who those kind of restructurations and new constitutions more frequently than just once every few centuries.
That's a big simplification. For scientists to be listened to by common people when they tell them to stop using units they'd been using their whole lives requires not just a lack of political opposition but an active support. The notion that "politicians used to be smarter" is actually quite correct. The social structure used to be different, back then there were profound divisions between social classes. People who would later go on to beccome politicians were ones born into the rich elite families, brought up with versatile education in an atmosphere of art and intellectualism. French revolution aimed at abolishing such social divisions, but it came from a society in which they were present. In some ironic aspects it was a product of them.
Today the stupid and loud masses have more power than they used to. It's the change democracy and internet brought us.

People weren't smarter, they were simplier and more obedient. For their lifes, it made no difference if distance is 1km or 0,62...miles or whatever. They adapted because why not.

Today's usage of units is way more complicated, so why still convert feet into miles/metres or °F into °C into K, therefore keep another possibilty for errors instead of growing up with basic SI units? Do you know how much easier you grow up if you convert cm into m instead of inch into feet? Makes no sense.
I think the number system thing was due to the fact that Algebra was all the rage with the middle eastern nations during their enlightenment and they were using ideas from India. But doing algebra with roman numerals is nigh impossible. So it was eventually adopted. At least thats what I 'think' it was. I think I remember reading that somewhere, but I can't be sure.
In Canada, we're somehow caught between the two systems. The majority of people continue to measure their weight in pounds and their height in feet and inches. But when you go to the butcher, you order 500 grams (roughly 1 pound) of ground beef, or whatever. Outside of our personal weight, almost everything else is measured in grams and kilograms. Oddly, it's still a pound of butter.
I think a somewhat similar 'revolution' or change in recent history was the euro. It was very disruptive at the time, everyone had to get used to a new currency, do the math in their head with how much it would be in the old one,...But a few short years later everyone got used to it and its convenience when travelling in the Europe and now gen z has never known anything else.
Fun fact, In 1793 a French standard metric is going to be delivered to Thomas Jefferson, but It was intercept and stolen by a group of British privateers(Pirates sponsored by the British to steal from the countries they don't like).
UK hasn't totally adopted the metric system. UK was "forced" to change a lot of things as part of our membership of EU. However, we have a hybrid approach. If you buy things in shops they will generally be sold in metric units. But clothes sizes still are generally given in inches. In pubs beer is still sold in pints. Speed limits are in miles per hour, nearly all road signs give distances in miles. Most people will give their height in feet and inches and weight in stones and pounds.
As an Greek we use metric measurement like 1 Liter bottle is 0.27 Gallon bottle in imperial measurement. And this unit of measurement confuses me a lot when I see it like other imperial units of measurement. But the metric is much better and easy in measurement, mathematics etc. Greetings from Greece!
Britain has many customary units, some obsolete, some still in use. Land area is no longer counted in 'hides', but 'the hundred' (of hides) is still to be found in many places, as small administrative units. Land is measured in both acres and the metric hectares (essentially the same name, but different sizes) A cricket pitch is still a 'chain' long, a nearby railway line has a bridge known as the '45 mile 6 chain' bridge on it's newly-made number plate. Measures of spirits are still in 'gills', recipes still say tablespoons, teaspoons, pinches etc. as quantities. Horses are still measured in 'hands', the money is in 'pounds' using the symbol £ which means livre, or 'weight' in French Latin, which dates back to the Roman's 'weight' of iron or bronze, which was the origin of the English 'one pound of iron to make 240 pennies'.
Don't forget- rods, poles, perches, furlongs ..... cubits. And what the hell is an acre-foot ? Also, Why the f* are US gallons smaller than Imperial gallons ? Aussie born '51 to Imperial system, decimal currency change during school, metric system later, still sometimes have to do conversions in head.
As Brit, I’m totally comfortable with both. If I measure some furniture it’s metric, as my generation were generally taught, my folks will still use inches. If someone asks me how far? It’s miles. Height is feet. Weight is stone, liquid can be pints or litres 🤷🏼♂️ I work in aviation. Aircraft altitude Height is feet, even in France, but metric in Russia and China. Mad. Distance is nautical miles, not statute miles! It’s all very chaotic!
Stone is one of the weirdest units I know. Like, people talk about different hands and feet being different size, but that's nothing compared to how much stones can vary in size and weight...
Nautical miles is just a name for an angle. It is 1 (angle-)minute at the equator by definition. So 1 degree is 60 nm (nautical miles), length of the equator is 21,600 nm = 40,003.2 km (nm = nautical mile, km = kilometer).
the funniest part is that all the none metric systems now days are calculated and defined by the metric system. Bucuse having a standard unit is just good.
What is fascinating and counter intuitive too is that our brains function with the units. I can estimate a human's height in CM very easily but I can never understand height measured in feets. It turns out the brain has the ability to work with units like meters, kilograms, seconds,etc. Because it has to use them all the time even though they map to nothing in reality.
you can measure height in feet really easy. if you wanna measure the height of someone just tell that person to lay down and walk over him from head to toe.
As an American, I grew up on the imperial system. After learning and using the metric system, I can process the metric measurements faster and more natural. I think a lot of individuals are missing this point.
As an american, meters per second is much more intuitive than miles per hour. Anyone can easily picture how fast meters per second is because they are much easier units to imagine due to their smaller size. Miles per hour is substantially harder to picture because the units are way to large picture.
m k s are the three si units. they build up all other units. for example the speed is messured in m/s while the acceleration is messured in m/s² or pressure is N/m² while N = kg*m/s² (because mass*acceleration) therefor is N/m²=kg*m/m²*s²=kg/m*s² as you can see it all comes down to this 3 units. thanks for watching my Ted talk, i am a physics teacher :)
Numbers aren't completely the same everywhere. We all understand the same numbers when they are written down like 100000 but while in English it's read as 100 1000 it's read as 10 10000 in e.g. Japanese. Also, 1 billion in German is 1000 times the English 1 billion. And in German we use a deicmal comma and the period serves to space out triplets of zeroes.
The "short" billion of 1,000,000,000 originated in the USA not the UK, with their financial institutions. "Long" billions, trillions etc as previously used in Britain and still used Europe make more sense as: billion = million x million trillion = million x million x million etc In this system the relationship between these meganumbers is much easier to understand.
@@robertfoulkes1832 Thanks Robert, I was going to say that this was not a UK thing. Growing up in Scotland in the 80s, our Billion was a million, million. It only changed gradually, in the UK, when the Gov decided to adopt the short Billion from 1974.
In the US, the metric system is used in addition to the custom units. In order to be able to have a say in international trade, the metric system must be used. But domestically, the custom units are retained. It is much easier to calculate and convert units in the metric system. Almost everything is divisible by 10, which means you only need to move the point Oh yes, the metric system has not prevailed for the days. It remains at 60 seconds, 60 minutes, 24 hours, 7 days a week, 28 to 31 days a month and 365.24 days a year
In the UK things like timetables are in 24hr format so avoiding any ambiguity but we'll refer to "five o'clock this afternoon", "five PM", etc.. In the USA your TV uses the 24hr clock as part of the broadcast, it's just displayed in AM/PM - it's also broadcast using UTC and then the local timezone offset applied. Your coinage is defined using the metric system as are your customary units such as the inch, pound, etc.. In fact most countries that use the metric system maintain some "customary" units. In the 1980s I was holidaying in France and asked at a grocers for 500g of apples. The assistant responded with "Un poid de pommes", i.e. "A pound of apples". In the UK, we'll still go for a pint of beer rather than half a litre of beer. The metric system is also consistent: a litre of water weighs 1kg, "back of envelope" calculations are incredibly simple whereas with the imperial system you have to deal with inconsistent conversion factors that you "just have to know"
@@gerardflynn7382 It's a French acronym - "Co-ordinated Universal Time" is the English translation. It's what GMT (Greenwich Mean Time) is called these days. There's a bit of politicking behind the name change but for all practical purposes they are the same.
I assume all the countries with 24 hour clock do that. For example, if someone asks when do you get off at work, saying at 5 or 4, etc. is completely normal. Of course in Finland we don't have the PM/AM, so we actually have to say in the evening/morning if it needs to be specified. In general people do stuff during the day, so there's no need to clarify what 3 o'clock means, unless you actually mean 03:00. I think the 24 hour format really shines in written form. It saves a lot of space, looks tidy, and you can't mistake 17:00 for 5:00 for example, as they're completely different numbers.
@@bobwightman1054 I don't think it's politics really. GMT is the solar time in Greenwich, whereas UTC is a time defined by an atomic clock independent of the earth's rotation. The two can differ about 1 or 2 seconds. Of course in daily life the difference is irrelevant.
@@bobwightman1054 It is neither a French nor an English acronym. In French it would be TUC (Temps Universel Coordonné). Since the French and Brits grudge each other the light in their eyes, they made the compromise of UTC.
US is actually using metric system, they also using imperial a lot unlike the UK we use both interchangeable swapping from one to the other like sometimes we may state a size in imperial then a few minutes later use metric like wood 4’x6’ or 1m x 2m were Americans just tend to stick with imperial Weight in metric and height in imperial measurements is a fascinating 🤨 combination that gets used in the UK, height in imperial system just gives easier numbers to remember and that’s basically why UK still uses both
Well it’s not practical to use both. I. One from Norway and has lived in the UK for 20 years, I can manage both but it creates problems as misunderstandings are common. For example most brits tend to hang on to just the millimetres, not using centimetre, decimetre or even metres. Not long ago I ordered a piece of slate from Wales, as I would do in Norway I gave measurements in millimetres for the thickness and centimetres for the length and width, as one would do in a proper “metric country”, but the stupid welsh guy just took all my measures in millimetres so it was totally wrong. I find brits even using millimetres for things that are several meters long which I find confusing, what is the point of that when it’s so much better to use the correct measurement. For example I only use millimetres if it’s quit small, less than 10 centimetres, and anything over one meter I always use meters. It’s the proper way of doing it as it creates less misunderstandings.
The Imperial, customary etc. system is useful in that it can be divided in more ways using standard sets of weights on a balance, or by gills, fluid ounces, pints, etc. Usually a quantity can be divided between 1, 2, 3, 4, 6. 8, 12, etc. Scaling also works, but results in some odd numbers, such as 3/16th of an inch on a plan being equal to one yard in reality, for example. That's really all of it. Doing everything by multiples of ten is actually simpler, works better, and calculations can be done by shifting decimal points only.
Actually the metric system came to America during the Jefferson Administration. But the Pirates intercepted the US copy of the standard meter and kilogram. What a better way to give the middle finger to King George than to destandardized his shoe size as the foot. Despite the Pirates the federal government has on and off preferred the metric system. It's the states and the states rights mentality that didn't want to conform to the feds and the world. In Ohio or certain counties within Ohio, it is forbidden to have a trade scale with a lb.xx/ lb-oz/kg conversion button. That's what most of the merchants tell me.
In my experience from talking to Americans. Many doesn't seem to know that they are using USC and not Impreial. They have many units and values that are the same. And now that they fixed the inch (Jan 1st 2023), I think it might just be the volume left. (Liquids) (United States Customary system used to have 2 different inches, that were almost the same length... but not quite. Their use varied based on what state you were in)
@@Kamonohashiii When it comes to volume they use the same names, but the rest is different. It's different values tied to the names, and even the numbers that goes into each other are different between them. And every measuring system is a variation of each other. Technically there might be a stronger defense for it just being a variation of Metric.
@@Kamonohashiii Imperial (and USC) no longer exist without Metric. It's defined as a conversion from Metric. The lengths themselves only exist in Metric..
the secret of metrics system is "1" LooK: 1l of pur water = 1Kg so one cube of 1m x 1m x 1m = 1m3 cubic ,if you put water inside you have 1000L = 1T so easy no?
You are right. The metric system is simpler. Everything is decimal based. If it raised with metric it is intuitive. Dors are 2 m tall. 2 m is the span from your fingertips to your breast, roundabout. As a metre raised guy i can't understand the complexity of the Imperial system.
You can use you freedom units all you want, but please, stop using this stupid date format MM/DD/YYYY. Sometimes Im looking at the date and i cant understand its meaning
'Murica actually used the decimal system a bit from the beginning: When the US dollar was established, the smallest coin was the "centidollar", shortened to "cents". Also, navigation at sea and in the air still uses the Nautical Mile that is based on the distance from the North pole to the equator. Each degree of longitude is 60 Nautical Miles. The Statue mile seems a superfluous invention, seeing that the ships originally sailing from the Empire to the Colonies already used Nautical miles for distance and Knots for speed (Nautical miles pr. hour).
@@njordholm Genau! :D Multiple meanings per word. Efficiency, baby. A Meter also describes an amount of beer, 10 to 15 x 0,2l (usually :D ) in a long wooden case. Besides, I say "meter" and not "metre" like the frenchies. Brits are almost as bad as them in not actually speaking what they write. Gloucestershire xD
@@friddevonfrankenstein I'd say English is even worse in its pronounciation. French is at least consistent most of the time: Sure, writing -ois and speaking -oa isn't the most practical, but at least every time I read -ois I know it's spoken -oa. For English just look at through, tough and though, spoken thru, tuff and thow.
I don’t think you can say the UK has fully embraced the metric system. Road sign distances are in miles, people use mph and mpg to describe a vehicle’s speed and economy, etc. But for anything in science or engineering it’ll be metric/SI units, which I think is also often the case in the USA these days.
Canada also has a different, complicated relationship with imperial. We use kilometers for road signs, but construction is typically done using imperial measurements. For food we often use a "metric pound" of 500g (instead of 454g). When I was making burger patties in a meat grinding plant we used pounds/ounces to measure them. The completed box would then have the total weight listed in kg.
When the meter was defined, a number of huge scientific expeditions to the north pole and to the equator were organized to measure the distance. One of them was led by Swedish astronomer Anders Celsius, known for inventing the centigrade temperature scale. Although he actually invented it the wrong way, with the boiling point of water at 0 degrees, and the freezing point at 100 degrees. Swedish scientist Carl von Linné realized the mistake and corrected it, but the temperature is still usually referred to as the Celsius temperature scale.
I can understand, that a "foot" seems more intuetive, cause its a body part and you have a reference... But for the other units its just a matter what you grew up whit and the metric system has the advantage, that its defined by universal constants.
I have learned BE at school, but for vocabulary like meter/metre and center/centre I choose AE which is the same in German. I apologise, you have to live with it. Would be better to use lowercase letters though, but I know it's a historical and deprecated name for this system, which later was updated to MKSA (Ampere added) and then merged into SI. Kilo just stands for 1000. For K in 'MKS' kilogram (1 kg = 1000 grams) is meant for the dimension of mass (M) and not Kelvin (K) which would be θ (Theta) instead as some probably think. (common [written italic], dimension symbol) = (unit symbol) length (l, L) = meter (m) mass (m, M) = kilogram (kg) time (t, T) = second (s) electric current [intensity] (I,I) = Ampere (A) thermodynamic temperature (T, θ [Theta]) = Kelvin (K) amount of substance (n, N) = Mol (mol) luminous intensity (lᵥ, J) = Candela (cd) As you see, it's easy to mix up the symbols if you don't use upper/lowercase. There was also the CGS-system (cm, g, s) which is no longer in use.
i'm English, I have a C&G in Motor Mechics and Carpentry & Joinery, both trades use a weird mix of the two systems, BA and Whitworth spanners and metric nuts and bolts. you measure construction in Metric but most construction materials are sold using Imperial units, ie plasterboard is sold in boards of 8ft X 4ft (1200 cm x600cm) 4inx 2in in wood, to buy the wood 100cm x 50cm is howits measured on site. grew up useing both system so i've had to find quick way to convert between Metric & Imperial, im 63 and its still a pain in the arse to convert. Distance and weight I find it easier to visualise in Imperial unit, but if it needs a precise and accurate calculation then i use metic, its just easier to caculate
2:59: They defined it as such and then sent surveyors to determine the actual length. Eratosthenes calculated the Earth's circumference in antiquity already. With the instruments available in the late 18th century, that was possible with a lot higher precision.
The metric system is easy also because cubic 10 cm (1 liter) of water is exactly 1 kg of weight. Another interesting fact is how they measured (over 200 years ago) the distance between the North Pole and the Equator. And it is easy to remember the length of the Equator - it is around 40,000 km (4 × 10,000 km)
The power of SI (metric) units comes into play when doing calculations. You need to select an electric motor to drive a hydraulic pump, and you are given the flow rate, the rated output pressure, and the efficiency of the pump. The motor needs to supply the output power of the pump and the efficiency losses, but what is the output power of the pump? Dimensional analysis tells us that a volume per unit time multiplied by a force per unit area is a force times a distance per unit time, or energy per unit time, which is power-- exactly what we are looking for! In the metric system, the unit of pressure is the kilopascal or one thousand newtons of force per square meter. The flow rate is in liters per second, but we need the volume to be cubic meters, there are one thousand liters in a cubic meter, so we divide liters per second by a thousand to get cubic meters per second. There is a thousand at the top and a thousand at the bottom, which cancel out so one kilopascal times one liter per second is a newton*meter per second which is exactly one watt, by definition. In American units, the pressure is in pounds per square inch and the flow rate is in (guessing) gallons per minute. The first conversion is going from gallons per minute to cubic inches per minute (I think that there are 225 cubic inches per gallon, which will allow us to calculate the power in inch*pounds per minute, which is a power, just not one that we are used to, so we would have to find the conversion ration from inch*pounds per minute to horsepower. Fortunately, one horsepower is both 746 watts and 396,000 inch*pounds per minute (550 foot*pounds per second).
Thailand hasn't fully adopt the metric system. You buy milk and gasoline in liter but paint in gallons. Distance is in meters but drills are in parts of an inch. The length of water pipes are in meters but the diameter is in inch. Area is measured in rai (1600 sq. meters) and ngan (400 sq. meters).
I'm just happy the US uses the same time system. Imagine if they swore by something else. Like 15 whiles in a day, 84 moments in a while, and 46 instances in a moment. That would just be dreadful for the rest of the world...
Fun fact: NASA, like all other scientists and engineers, uses metric units in its calculations for space missions because it makes them easier and less error-prone. For example, converting inches to feet to yards to miles requires several different conversion numbers, but millimeters to meters to kilometers is just moving the decimal point. The errors come when people try to translate to/from the imperial units, or get mistaken about what units a particular number is expressing (e.g. 45 pints is less than 45 liters is less than 45 gallons (UK or US?) etc.).
Britain adopted the metric system around the time we joined the European Economic Community,Europe used the metric system so it made trade with them them much easier when UK adopted metric system,most weights, measurements, standards for appliances,cars , building materials etc were the ones used in EEC ,saved a lot of time and trouble.Somethig the UK is starting realise again now we have left the EEC and import/export tariffs and regulations have been reintroduced .

It started with a failed Mars mission, but there was yet another space flight issue -- I believe it was about 20 yrs. ago -- where a big accessory part of the ISS to be jointly built by several partners could only be finished with a major delay because NASA took the meaurements of the joint construction plan as inches (1 in = 2.54 cm) instead of centimeters. NASA implemented major precautions to never let this happen again. I love your posts! BTW, what happened to your last name...? All best from Germany
I have once a contract in Canada, and all the technical drawings were in imperial units, we were supplied with inch/feet measurment tapes as well that was the most irritating thing in my whole fitter/welders life, to use these. and I have all the time that question in mind - "how US build up such an impressisve industry and stuff using measurment scale with its smallest unit commonly used is almost twice bigger than metrics smallest unit - a milimeter.. how one can do precise things with instruments having smallest details in 1/16 of inch.. and the whole idea of multiplying by 16 and not using equal values for base units.." I used to have sometimes precise projects, with indication to keep dimension in half-milimeter range..
I grew up with Imperial, but am now used to metric, and can think in both. Yes, pounds and feet are easier for me, but I'm nearly 70 and can manage to convert miles, pounds, Fahrenheit to metric , and use the 24 hour clock with no problem. France did try to change the calendar, rename the months and days, and have 10 days a week, 10 hours a day, etc. It did not go well.
Still there are conversions because they failed to adopt decimal time. The 3600 second unit of an hour is used for speed measurements (km/h) and electric energy (kWh). With decimal time, they could have been powers of ten of the SI units metres per second and joules.

in fact
Eratosthenes was a Greek mathematician and astronomer of the 3rd century BC
Jesus Christ (born in -276, died in -194). He lived in Alexandria where, as director
for several years from the great library of Alexandria, he had access to
practically all the mathematical and scientific literature of his time. He has
left some original works, whose measurement, remarkably precise for
the time, of the earth's circumference.
The measurement of the angle between the stick and the sun's rays should be taken at
Alexandria at noon on the day of the summer solstice.
This allows the comparison with Syènewhere, the city being on the Tropic of Cancer, the rays of the sun are perfectly vertical at this time.
On the geometric model we see the extension of the ray of the sun which, from Syene, goes straight towards the center of the earth. In fact, this was known by Eratosthenes.
At noon on the day of the summer solstice, there was no shade at the bottom of a well in Syène, the sun being exactly vertical to the well.
Essentially, to measure the earth's circumference, Eratosthenes has
used two commonplace things in his time:
- a stick planted vertically in Alexandria and whose angle with the rays
solar is equal to the angle at the center of the earth between Alexandria and Syene, as the
geometric model shows it.
- a camel to measure the distance between the two cities.
Camels were reputed to have a very even pitch. Several hypotheses exist:
perhaps that Eratosthenes simply measured the average distance traveled by a camel in a day and multiplied by the number of days the journey takes,
maybe he used a step counter (a bematist, a real profession to the time to measure the distances) in which case the steps measured could have been those
of a camel, probably, but perhaps those of a man.

You order it depending on length ... either the longest first, going down to the shortest (YY/MM/DD) or the shortest first, going up to the longest (DD/MM/YY) ...
The month is ALWAYS in the middle ... not doing that makes no sense at all >.
The main problem with Imperial units is, that you have different units for the same task: measuring length for instance. You have inches, feet, yards and miles, each of them arbitrarily defined, and thus you have 12 inches in a foot, but 3 feet in a yard and 1760 yards in a mile. In SI units, there is exactly one unit of length, the meter. Kilometer or Millimeter are no new units, just meters times a power of 10. In imperial units, you have units of area and units of volume, which are not compatible with the units of length. A gallon is not a cubic foot or something easy, but 128 fluid ounces, and 231 cubic inches. While 128 might be somehow understandable (2 to the power of 7), but why 231 cubic inches? 3 times 77 cubic inches? Where does the 77 come from?
In SI units, the unit of volume is the cubic meter: 1 meter of length times 1 meter of height times 1 meter of depth. Quick and easy to remember.
Imperial units were designed before Isaac Newton discovered the fundamental Laws of Mechanics and the Law of Gravity. Before Isaac Newton, scientists didn't notice that mass is a property of a body, but weight is the force on a body in a gravitational field. Thus, pound was used for both the mass and the weight. Now, we have pound-force, but again, arbitrarily defined as the force a body of a mass of 1 pound experiences in the average gravitational field of the Earth at the Earth's surface. In SI units, the unit of Mass is kilogram, and according to Newtons first law, Force is the acceleration of a mass, thus Force is measured in kilogram times meters per square second, as meters per square second is the unit of acceleration.
you just blow my mind out of my skull, what a mess they created for themself

EDIT this comment has been altered due to sevral mathematical error in conversion between imperial units and metric, at the time of writing i used ml as an one dimentional value..but it represent an 3 dimensional volume, this has now been corrected
------------DID-I-MENTION-IMPERIAL-UNITS-IS-A-MESS--------------------
Since 1985: The Weights and Measures Act 1985 defined a gallon to be exactly 4.54609 L
...also ALL Imperial units is now defined by the SI(Metric system) to avoid errors as faar as possible till countries still depending on it has switched over..
a few corrections
1 Imperial fluid ounce = 28,4130625 ml (milli-liter) =
(1,7338714549476343047174283324945 cubic inches)
1 Imperial fluid ounce = 0.96076 US Customary Fluid ounces
1 Fluid Ounce (28,4130625 ml)
1 Pint = 20 fl oz. (568.26125 ml)
1 Gallon = 160 fl oz.(4546.09 ml) =
277,41943279162148875478853319911 square inch
also dry/wet weight and volume was different units, but since 1824 act joined.
still grain, fluid, minerals, valuble metalls and gemstones(diomonds, rubines etc..)
are all different units of measurment 1 gem ounce is not equal to 1 fluid ounce is not equal to 1 grain ounce .... comfusing as f'... and if u dont know the chance for errors is enrmous
even baking using imperial units is a pain 1 oz salt is not equal to 1 oz grain/flour is not equal to 1 oz water.... try doing scientiffic calculations and ur in for a treat...
...even scientists that grew up with this obsolete system constantly makes misstakes in calculations... (not surpricing)
in metric there is one unit the meter,
deci(1/10), centi(1/100), milli(1/1000), micro(1/1000000) is just describing fractions of the unit, converting and doing calculations as far easier.
1 Liter = Cubic deci-meter = 1Kg, and 1Kg accelerates towoard center of earth with the force of 1G= 9.82Nm/S2...its a connected system based on science...
And t make matters worse, a US gallon is not the same as a UK gallon.
Btw.: Even the imperial system is now based on metric. An inch is 2.54 centimeters. Not just about that, but exactly, that's how the inch is defined now. So every change to metric (for example more exact measurements leading to a change in the 10th digit) carry over to imperial automatically. Imperial just rides on top of metric now, for those people who like it a bit more complicated.

I'm from Belgium and as an engineer I'm very familiar with the metric system of course and a bit with the medievel (sorry for the word) system. I cannot understand why it is still used. But in fact, compare it with the European currency: before 2002 every country in Europe had its own currency. Every time you travelled you needed to switch currency and you didn't know exactly how much money you spent. In 2002 we started to use the Euro. In the beginning we had to adapt to this new currency, but after a few years everybody got used to it and now we all know exactly the value of the Euro. If we Europeans can change our money, I'm sure the Americans can also change from imperial to metric. What are you guys waiting for !
Becouse America is the greates country of the world with the best systems, helathcare and what not hahahah those fools are sooo brainwashed

The mere fact that you're here shilling for it shows how much of an NPC you truly are.
The euro has nothing to do with this subject, measurements and currency just aren't the same at all. 1 reason to resist the change is that it would be expensive. Every single road sign with miles would become outdated, and they might need road signs with both measurements in the transition period. Every car with a mile meter would also become outdated after the full transition. I'm sure there are tons of other examples of where it will cost for both the government, and the people.
It just isn't that simple of a deal, and rarely things are THAT simple when you really look into it.

Favorite metric system quote is by Josh Bazell. “In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade-which is 1 percent of the difference between its freezing point and its boiling point. ... Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go f**k yourself,’ because you can’t directly relate any of those quantities.”
Everything has a rational relationship with everything else.
4:30 actually there was originally an effort to make time metric, too. A day would have been divided into 10 hours, each hour into 100 minutes and each minute into 100 seconds.
The reason this change was rolled back after a very short time was that it would have required to replace all public clocks, which would have been prohibitively expensive. So at the end of the day, the second is a metric units, and the derived units (minute, hour, day, year) continue to be officially authorized derived units, despite not being based on the unit 10.
yeah good luck making years and months metric
i disagree with categorizing a second as a metric unit (for now).
because it's used by the metric system to define units, it's now a set amount of time and not the 1/86,400th of a day.
days are getting ever so slightly longer, so they had to preserve it's value for the integrity of metric system.
metric seconds will become a thing once earth's days are longer than 86400 metric seconds long, but for now it's too miniscule to worry about (we struggle to be accurate enough that this would even matter)
@@PyrokineticFire1 the second totally is one of the SI basic units.
However, it ceased being defined as the 86,400th part of the day a long time ago, and for the reasons you cited - the "Earth day" not being a universal, unchanging constant.
Nowadays the second is defined by the physical properties of a Cesium isotope. The definition would still work even if Earth ceased to exist.

This is not a "metric is more intuitive" case. This is "what I grew up with and is everywhere around me is more intuitive" situation.
This is the excuse especially for temperatures, of course to them °F feels more human, they've not grown up with °C and made the association that 30° is really hot when to them it means it's cold. To me the connection of the freezing and boiling points of water feels more generally intuitive. The most insuler comment I've heard is that 0°f - 100°f is the bearable range, anything beyond that isn't bearable, which ignores that that is somewhat subjective to an individuals perception rather than a global constant (I'm aware water purity and atmospheric pressure does make a difference between freezing and boiling points of water, which is why Celsius is based on pure water at average sea-level pressures, water will boil at lower temperatures up on mountains, so you'd need a pressurised kettle to make a good cup of tea on mount Everest 😅)

It actually took years to measure the first meter. Since they couldn't measure the whole length from northpole to the equator, they measured from dunkirk to barcelona which is roughly 1/10 of the length. They did it using methods of triangulation and modern Equipment
These were indeed large scientific projects of the day; another one was the triangulation survey of the Struve Geodetic Arc, stretching from the coast of the Arctic Ocean to the Black Sea over 2800 km to the south.
I mean to be fair we had a pretty good estimate of the circumference back in the 3rd century BC. Eratosthenes measurement was a little on the large size with the true value being just bellow the lower bound of his estimate but not by much. His estimate was in the region of 40,250 to 45,900 kilometres, the actual values are 40,008 km polar and 40,075 km equatorial. But still you know this was done with a couple of sticks and a camel to travel between observation points over 2,200 years ago. Over the years this was further refined with more data from more observations but it makes it really depressing that modern humans have trouble figuring out such simple things with advanced computers and the internet etc which ancient people were figuring out with sticks, camels, and an abacus thousands of years ago.

During Napoleon's rule the Grand Duchy of Baden in south west Germany became an ally of France. Tulla was an officer and civil engineer in the army of the Grand Duke. The Ecole Polytechnique in Paris was founded as a military academy during the French Revolution and Tulla received permission to stay there for studies for some time. The Ecole Polytechnique enjoyed the reputation as the leading engineering school in the world (it's still very reputable). Returning from Paris Tulla initiated two things:
firstly he recommended to the Grand Duke to establish an engineering academy along the principles of the Ecole Polytechnique, the Technical University of Karlsruhe. And secondly he recommended giving up old unit systems in favour of the French system with Meter, Kilogramm, and Second (MKS) which became the Systeme International des poinds et messures (SI).
The next to adopt the MKS system was the German Kingdom of Württemberg, east of Baden. After the wars with Napoleon and after the Congress of Vienna, industrialisation was picking up speed in German countries and the advantage of the French metric system was recognized gradually all over Germany.

@Peter de Jong Please note that I was talking about the 1800s and early 1900s. No wars were started in my part of the world at that time. The brutality and insanity of the middle ages came back with socialism! Say in Sovjet, China, Germany (National Socialists), Italy (the fascism led by marxist Mussolini) and so on.
Postmodern deconstructivists are still thinking in very marxist terms, so much of that totalitarian mentality remains.
I'm optimistic when/if there are reasons for it, not because you say I should be... :D
Also, most of the scientific groundwork for our technological achievements during the last 50 years was done before WWII. And the mathematical grounds for it was largely invented and sorted out around the 1700s.
@Peter de Jong Also keep in mind that wars are often an impulse for developing new technologies and ideas. Nothing is a better proof that "Knowledge is Power" than an arm race, in which developing a technology faster than your enemy gives you advantage and can even help you win the war. Like the radar, for example, that allowed the British to detect German airplane bombers approaching before they got close enough to be visible. Or read about all the inventions Archimedes came up with to protect the city of Syracuse sieged by Romans. Wars end, but knowledge remains, and can then help us grow in the times of peace.
@Peter de Jong _"Archimedes is an ancient myth"_
Oh, you are one of _those_ people? ;q What else? Rome didn't exist either?
Dude, what are you even talking about. If you made just the basic research (i.e. on Wikipedia), you would find TONS of historical sources documenting Archimedes's life, as well as his involvement in the siege of Syracuse during the Second Punic War, and his inventions that helped protect the city. Not only from Greek sources, but from Roman sources as well.
Also I never said that war is good. I just said that despite all its atrocities, it often causes development of science and engineering because "a need is the mother of inventions". During the time of peace, science might thrive too, but there isn't that much pressure on developing it and even less pressure on applying it. Ideas might develop, but they're not necessarily converted to new technologies until there's an actual need to do that. (Like with the radar.)
Anyway, I don't think that you're a good partner for me to discuss such things, so let me end on that note.
Portugal was one of the first to adopt metrics, and even to this day, villagers/old people still talk about the old measures that are actually not in use for almost 2 centuries. When they talk about them, they are aware of the equivalent metric unit.
This is true. Some of my grandparents still talk about some of those measures when they talk, although they don't really use them at all. Those ancient measurements are also very present in traditional and old songs as well.

Even in a country as small as the Netherlands, people choose to define their own standards - until the ridiculousness enforced change. Like how clocks were not synchronised, which made "I’ll be arriving at noon" a very flexible concept, from one town to another.
In Sweden it took the building of the railroads to get a unified time - putting two trains on the same line because the two ends had different opinions on what the time was, was bad ...
For axwhile there were 4 different times one might've had to consider in Sweden; the _local time_ Ömsolar time (based on longitude, differing 45 minutes between Haparanda and Strömstad, 24 minutes between the 2 largest cities of Stockholm and Gothenburg.
_Railroad time_, based on Gothenburg time, was chosen for the railroads, and many stations had clocks w/ dual minute hands (local and railroad).
_Telegraph time_ I suspect its use in trades required everyone to be able to agree to what time something was sent.@
_Navigation time_ - likely to avoid the need of local tables for things like celestial navigation and tide charts.
In 1878 a single time was introduced (based on a compromise, as Stockholm, capital, wouldn't see railroad/Gothenburg time, over Stockholm time - so a compromise somewhere in-between was agreed.

2:30 It's not so much that people were smarter, or that politicians were. But it's that a Revolution was the perfect context to pass radical changes, without the weight of such an elite class caring more about their place than policies and people. Scientists were simply listened to, because there wasn't a political motivation to not do so. That's also why the most advanced and progressive societies are those who those kind of restructurations and new constitutions more frequently than just once every few centuries.
That's a big simplification. For scientists to be listened to by common people when they tell them to stop using units they'd been using their whole lives requires not just a lack of political opposition but an active support.
The notion that "politicians used to be smarter" is actually quite correct. The social structure used to be different, back then there were profound divisions between social classes. People who would later go on to beccome politicians were ones born into the rich elite families, brought up with versatile education in an atmosphere of art and intellectualism. French revolution aimed at abolishing such social divisions, but it came from a society in which they were present. In some ironic aspects it was a product of them.
Netherlands here, why am i not surprised we standardised it asap 😂
You are so right about the smartness of people back in those days. Common sense and practicality were considered which are not in use today.
Today the stupid and loud masses have more power than they used to. It's the change democracy and internet brought us. Would have been better if people actually tried to improve themselves now that we have a chance to, but the majority don't, yet feel entitled that their opinion counts for something (it shouldn't by default just if you have knowledge/experience in the subject and a reasonably defendable position).
People weren't smarter, they were simplier and more obedient. For their lifes, it made no difference if distance is 1km or 0,62...miles or whatever. They adapted because why not. While Americans don't because they want to be special, they still want a reminder for their connection to the monarchy (Americans deeply want to be ruled by a king) and the world has to adapt to them and not the other way around, like a defient child.
mate, most people didnt have high school education
@@obinator9065 Sure, but common sense was present which cannot be acquired at any school.
@@obinator9065 What exactly does that mean? Now much more people have highschool education, so why do Americans still not adapt?
Or did they adapt in Europe because they were not in highschool back in the day? The usage was way simplier, for everyday stuff such as weight or distances.
Today's usage of units is way more complicated, so why still convert feet into miles/metres or °F into °C into K, therefore keep another possibilty for errors instead of growing up with basic SI units? Do you know how much easier you grow up if you convert cm into m instead of inch into feet? Makes no sense.

Imperial system is very useful in case of shoe sizes. You always know it's one foot.
I can't imagine doing science without the metric system or something similar.
I think the number system thing was due to the fact that Algebra was all the rage with the middle eastern nations during their enlightenment and they were using ideas from India.
But doing algebra with roman numerals is nigh impossible. So it was eventually adopted. At least thats what I 'think' it was. I think I remember reading that somewhere, but I can't be sure.
The fact that an imperial gallon is different from a US Gallon us all you need to know
In Canada, we're somehow caught between the two systems. The majority of people continue to measure their weight in pounds and their height in feet and inches. But when you go to the butcher, you order 500 grams (roughly 1 pound) of ground beef, or whatever. Outside of our personal weight, almost everything else is measured in grams and kilograms. Oddly, it's still a pound of butter.
I think a somewhat similar 'revolution' or change in recent history was the euro. It was very disruptive at the time, everyone had to get used to a new currency, do the math in their head with how much it would be in the old one,...But a few short years later everyone got used to it and its convenience when travelling in the Europe and now gen z has never known anything else.
Fun fact, In 1793 a French standard metric is going to be delivered to Thomas Jefferson, but It was intercept and stolen by a group of British privateers(Pirates sponsored by the British to steal from the countries they don't like).
- What's your shoe size?
- A... foot? Duh.
UK hasn't totally adopted the metric system. UK was "forced" to change a lot of things as part of our membership of EU. However, we have a hybrid approach. If you buy things in shops they will generally be sold in metric units. But clothes sizes still are generally given in inches. In pubs beer is still sold in pints. Speed limits are in miles per hour, nearly all road signs give distances in miles. Most people will give their height in feet and inches and weight in stones and pounds.
The same everywhere. In every country there are customary units used in some trades or activities, even in france.
Point being that UK people have no idea how long 200km drive is and how much 1kg of chicken looks like on a plate? Cause you can know both
The numbers sizes of clothes actually have units??? I thought it was just random numbers... And the only one I can trust are for shoes and jeans...
@@Mobin92 Collar width of shirts are given in centimeters or inch.
As an Greek we use metric measurement like 1 Liter bottle is 0.27 Gallon bottle in imperial measurement. And this unit of measurement confuses me a lot when I see it like other imperial units of measurement. But the metric is much better and easy in measurement, mathematics etc. Greetings from Greece!
I would think that america want to get rid off measurment units of former opressor
Britain has many customary units, some obsolete, some still in use.
Land area is no longer counted in 'hides', but 'the hundred' (of hides) is still to be found in many places, as small administrative units.
Land is measured in both acres and the metric hectares (essentially the same name, but different sizes)
A cricket pitch is still a 'chain' long, a nearby railway line has a bridge known as the '45 mile 6 chain' bridge on it's newly-made number plate.
Measures of spirits are still in 'gills', recipes still say tablespoons, teaspoons, pinches etc. as quantities.
Horses are still measured in 'hands', the money is in 'pounds' using the symbol £ which means livre, or 'weight' in French Latin, which dates back to the Roman's 'weight' of iron or bronze, which was the origin of the English 'one pound of iron to make 240 pennies'.
Don't forget- rods, poles, perches, furlongs ..... cubits. And what the hell is an acre-foot ?
Also, Why the f* are US gallons smaller than Imperial gallons ?
Aussie born '51 to Imperial system, decimal currency change during school, metric system later,
still sometimes have to do conversions in head.
As Brit, I’m totally comfortable with both. If I measure some furniture it’s metric, as my generation were generally taught, my folks will still use inches. If someone asks me how far? It’s miles. Height is feet. Weight is stone, liquid can be pints or litres 🤷🏼♂️ I work in aviation. Aircraft altitude Height is feet, even in France, but metric in Russia and China. Mad. Distance is nautical miles, not statute miles! It’s all very chaotic!
Stone is one of the weirdest units I know. Like, people talk about different hands and feet being different size, but that's nothing compared to how much stones can vary in size and weight...
Nautical miles is just a name for an angle. It is 1 (angle-)minute at the equator by definition. So 1 degree is 60 nm (nautical miles), length of the equator is 21,600 nm = 40,003.2 km (nm = nautical mile, km = kilometer).
in USA is in use some pure metric units. Eg: volt and kWh
the funniest part is that all the none metric systems now days are calculated and defined by the metric system.
Bucuse having a standard unit is just good.
What is fascinating and counter intuitive too is that our brains function with the units. I can estimate a human's height in CM very easily but I can never understand height measured in feets.
It turns out the brain has the ability to work with units like meters, kilograms, seconds,etc. Because it has to use them all the time even though they map to nothing in reality.
you can measure height in feet really easy. if you wanna measure the height of someone just tell that person to lay down and walk over him from head to toe.
As an American, I grew up on the imperial system. After learning and using the metric system, I can process the metric measurements faster and more natural. I think a lot of individuals are missing this point.
As an american, meters per second is much more intuitive than miles per hour. Anyone can easily picture how fast meters per second is because they are much easier units to imagine due to their smaller size. Miles per hour is substantially harder to picture because the units are way to large picture.
m k s are the three si units. they build up all other units. for example the speed is messured in m/s while the acceleration is messured in m/s² or pressure is N/m² while N = kg*m/s² (because mass*acceleration) therefor is N/m²=kg*m/m²*s²=kg/m*s² as you can see it all comes down to this 3 units. thanks for watching my Ted talk, i am a physics teacher :)
Numbers aren't completely the same everywhere. We all understand the same numbers when they are written down like 100000 but while in English it's read as 100 1000 it's read as 10 10000 in e.g. Japanese.
Also, 1 billion in German is 1000 times the English 1 billion.
And in German we use a deicmal comma and the period serves to space out triplets of zeroes.
that "billion" being 1000 times bigger than english is normal in many european countries
The "short" billion of 1,000,000,000 originated in the USA not the UK, with their financial institutions.
"Long" billions, trillions etc as previously used in Britain and still used Europe make more sense as:

In the US, the metric system is used in addition to the custom units. In order to be able to have a say in international trade, the metric system must be used. But domestically, the custom units are retained.
It is much easier to calculate and convert units in the metric system.
Almost everything is divisible by 10, which means you only need to move the point
Oh yes, the metric system has not prevailed for the days.
It remains at 60 seconds, 60 minutes, 24 hours, 7 days a week, 28 to 31 days a month and 365.24 days a year
In the UK things like timetables are in 24hr format so avoiding any ambiguity but we'll refer to "five o'clock this afternoon", "five PM", etc..
In the USA your TV uses the 24hr clock as part of the broadcast, it's just displayed in AM/PM - it's also broadcast using UTC and then the local timezone offset applied. Your coinage is defined using the metric system as are your customary units such as the inch, pound, etc..
In fact most countries that use the metric system maintain some "customary" units. In the 1980s I was holidaying in France and asked at a grocers for 500g of apples. The assistant responded with "Un poid de pommes", i.e. "A pound of apples". In the UK, we'll still go for a pint of beer rather than half a litre of beer.
The metric system is also consistent: a litre of water weighs 1kg, "back of envelope" calculations are incredibly simple whereas with the imperial system you have to deal with inconsistent conversion factors that you "just have to know"
UTC??
@@gerardflynn7382 It's a French acronym - "Co-ordinated Universal Time" is the English translation. It's what GMT (Greenwich Mean Time) is called these days. There's a bit of politicking behind the name change but for all practical purposes they are the same.
I assume all the countries with 24 hour clock do that. For example, if someone asks when do you get off at work, saying at 5 or 4, etc. is completely normal. Of course in Finland we don't have the PM/AM, so we actually have to say in the evening/morning if it needs to be specified. In general people do stuff during the day, so there's no need to clarify what 3 o'clock means, unless you actually mean 03:00.
I think the 24 hour format really shines in written form. It saves a lot of space, looks tidy, and you can't mistake 17:00 for 5:00 for example, as they're completely different numbers.
@@bobwightman1054 I don't think it's politics really. GMT is the solar time in Greenwich, whereas UTC is a time defined by an atomic clock independent of the earth's rotation. The two can differ about 1 or 2 seconds. Of course in daily life the difference is irrelevant.
@@bobwightman1054 It is neither a French nor an English acronym. In French it would be TUC (Temps Universel Coordonné). Since the French and Brits grudge each other the light in their eyes, they made the compromise of UTC.
US is actually using metric system, they also using imperial a lot unlike the UK we use both interchangeable swapping from one to the other like sometimes we may state a size in imperial then a few minutes later use metric like wood 4’x6’ or 1m x 2m were Americans just tend to stick with imperial
Weight in metric and height in imperial measurements is a fascinating 🤨 combination that gets used in the UK, height in imperial system just gives easier numbers to remember and that’s basically why UK still uses both
Shhh… dumb folks haven’t seemed to have figured it out yet. They think by sitting there saying everyone else is dumb, it excuses their own ignorance.
Well it’s not practical to use both. I. One from Norway and has lived in the UK for 20 years, I can manage both but it creates problems as misunderstandings are common. For example most brits tend to hang on to just the millimetres, not using centimetre, decimetre or even metres. Not long ago I ordered a piece of slate from Wales, as I would do in Norway I gave measurements in millimetres for the thickness and centimetres for the length and width, as one would do in a proper “metric country”, but the stupid welsh guy just took all my measures in millimetres so it was totally wrong. I find brits even using millimetres for things that are several meters long which I find confusing, what is the point of that when it’s so much better to use the correct measurement. For example I only use millimetres if it’s quit small, less than 10 centimetres, and anything over one meter I always use meters. It’s the proper way of doing it as it creates less misunderstandings.
The Imperial, customary etc. system is useful in that it can be divided in more ways using standard sets of weights on a balance, or by gills, fluid ounces, pints, etc.
Usually a quantity can be divided between 1, 2, 3, 4, 6. 8, 12, etc.
Scaling also works, but results in some odd numbers, such as 3/16th of an inch on a plan being equal to one yard in reality, for example.
That's really all of it.
Doing everything by multiples of ten is actually simpler, works better, and calculations can be done by shifting decimal points only.
Actually the metric system came to America during the Jefferson Administration. But the Pirates intercepted the US copy of the standard meter and kilogram.
What a better way to give the middle finger to King George than to destandardized his shoe size as the foot.
Despite the Pirates the federal government has on and off preferred the metric system. It's the states and the states rights mentality that didn't want to conform to the feds and the world.
In Ohio or certain counties within Ohio, it is forbidden to have a trade scale with a lb.xx/ lb-oz/kg conversion button. That's what most of the merchants tell me.
In my experience from talking to Americans. Many doesn't seem to know that they are using USC and not Impreial.
They have many units and values that are the same. And now that they fixed the inch (Jan 1st 2023), I think it might just be the volume left. (Liquids)
(United States Customary system used to have 2 different inches, that were almost the same length... but not quite. Their use varied based on what state you were in)
I imagine that just makes whole thing worse and even more confusing
It's just a variation of the imperial. It doesn't change much
@@Kamonohashiii When it comes to volume they use the same names, but the rest is different. It's different values tied to the names, and even the numbers that goes into each other are different between them.
And every measuring system is a variation of each other. Technically there might be a stronger defense for it just being a variation of Metric.
@@Telruin metric have nothing to do with imperial
@@Kamonohashiii Imperial (and USC) no longer exist without Metric. It's defined as a conversion from Metric. The lengths themselves only exist in Metric..

You are right. The metric system is simpler. Everything is decimal based. If it raised with metric it is intuitive. Dors are 2 m tall. 2 m is the span from your fingertips to your breast, roundabout. As a metre raised guy i can't understand the complexity of the Imperial system.

'Murica actually used the decimal system a bit from the beginning: When the US dollar was established, the smallest coin was the "centidollar", shortened to "cents". Also, navigation at sea and in the air still uses the Nautical Mile that is based on the distance from the North pole to the equator. Each degree of longitude is 60 Nautical Miles. The Statue mile seems a superfluous invention, seeing that the ships originally sailing from the Empire to the Colonies already used Nautical miles for distance and Knots for speed (Nautical miles pr. hour).

I don’t think you can say the UK has fully embraced the metric system. Road sign distances are in miles, people use mph and mpg to describe a vehicle’s speed and economy, etc. But for anything in science or engineering it’ll be metric/SI units, which I think is also often the case in the USA these days.
Canada also has a different, complicated relationship with imperial.
We use kilometers for road signs, but construction is typically done using imperial measurements.
For food we often use a "metric pound" of 500g (instead of 454g). When I was making burger patties in a meat grinding plant we used pounds/ounces to measure them. The completed box would then have the total weight listed in kg.
When the meter was defined, a number of huge scientific expeditions to the north pole and to the equator were organized to measure the distance. One of them was led by Swedish astronomer Anders Celsius, known for inventing the centigrade temperature scale. Although he actually invented it the wrong way, with the boiling point of water at 0 degrees, and the freezing point at 100 degrees. Swedish scientist Carl von Linné realized the mistake and corrected it, but the temperature is still usually referred to as the Celsius temperature scale.
I can understand, that a "foot" seems more intuetive, cause its a body part and you have a reference...
But for the other units its just a matter what you grew up whit and the metric system has the advantage, that its defined by universal constants.
M = meter, K =kilo, S =second
*metre
I have learned BE at school, but for vocabulary like meter/metre and center/centre I choose AE which is the same in German. I apologise, you have to live with it.
Would be better to use lowercase letters though, but I know it's a historical and deprecated name for this system, which later was updated to MKSA (Ampere added) and then merged into SI.
Kilo just stands for 1000.
For K in 'MKS' kilogram (1 kg = 1000 grams) is meant for the dimension of mass (M) and not Kelvin (K) which would be θ (Theta) instead as some probably think.
(common [written italic], dimension symbol) = (unit symbol)
length (l, L) = meter (m)
mass (m, M) = kilogram (kg)
time (t, T) = second (s)
electric current [intensity] (I,I) = Ampere (A)
thermodynamic temperature (T, θ [Theta]) = Kelvin (K)
amount of substance (n, N) = Mol (mol)
luminous intensity (lᵥ, J) = Candela (cd)
As you see, it's easy to mix up the symbols if you don't use upper/lowercase.
There was also the CGS-system (cm, g, s) which is no longer in use.
i'm English, I have a C&G in Motor Mechics and Carpentry & Joinery, both trades use a weird mix of the two systems, BA and Whitworth spanners and metric nuts and bolts. you measure construction in Metric but most construction materials are sold using Imperial units, ie plasterboard is sold in boards of 8ft X 4ft (1200 cm x600cm) 4inx 2in in wood, to buy the wood 100cm x 50cm is howits measured on site. grew up useing both system so i've had to find quick way to convert between Metric & Imperial, im 63 and its still a pain in the arse to convert.
Distance and weight I find it easier to visualise in Imperial unit, but if it needs a precise and accurate calculation then i use metic, its just easier to caculate

only 3 countries still use imperial..... and that people's own feet have different sizes.

The metric system is easy also because cubic 10 cm (1 liter) of water is exactly 1 kg of weight.
Another interesting fact is how they measured (over 200 years ago) the distance between the North Pole and the Equator. And it is easy to remember the length of the Equator - it is around 40,000 km (4 × 10,000 km)

The power of SI (metric) units comes into play when doing calculations. You need to select an electric motor to drive a hydraulic pump, and you are given the flow rate, the rated output pressure, and the efficiency of the pump. The motor needs to supply the output power of the pump and the efficiency losses, but what is the output power of the pump?
Dimensional analysis tells us that a volume per unit time multiplied by a force per unit area is a force times a distance per unit time, or energy per unit time, which is power-- exactly what we are looking for! In the metric system, the unit of pressure is the kilopascal or one thousand newtons of force per square meter. The flow rate is in liters per second, but we need the volume to be cubic meters, there are one thousand liters in a cubic meter, so we divide liters per second by a thousand to get cubic meters per second. There is a thousand at the top and a thousand at the bottom, which cancel out so one kilopascal times one liter per second is a newton*meter per second which is exactly one watt, by definition.
In American units, the pressure is in pounds per square inch and the flow rate is in (guessing) gallons per minute. The first conversion is going from gallons per minute to cubic inches per minute (I think that there are 225 cubic inches per gallon, which will allow us to calculate the power in inch*pounds per minute, which is a power, just not one that we are used to, so we would have to find the conversion ration from inch*pounds per minute to horsepower. Fortunately, one horsepower is both 746 watts and 396,000 inch*pounds per minute (550 foot*pounds per second).

Fun fact: NASA, like all other scientists and engineers, uses metric units in its calculations for space missions because it makes them easier and less error-prone. For example, converting inches to feet to yards to miles requires several different conversion numbers, but millimeters to meters to kilometers is just moving the decimal point. The errors come when people try to translate to/from the imperial units, or get mistaken about what units a particular number is expressing (e.g. 45 pints is less than 45 liters is less than 45 gallons (UK or US?) etc.).

1 Meter is not 1/10'000'000 of distance between pole and equator, it is 1/10'000.
It started with a failed Mars mission, but there was yet another space flight issue -- I believe it was about 20 yrs. ago -- where a big accessory part of the ISS to be jointly built by several partners could only be finished with a major delay because NASA took the meaurements of the joint construction plan as inches (1 in = 2.54 cm) instead of centimeters. NASA implemented major precautions to never let this happen again.

Myanmar is actually in the process of switching to Metric.
I have once a contract in Canada, and all the technical drawings were in imperial units, we were supplied with inch/feet measurment tapes as well
that was the most irritating thing in my whole fitter/welders life, to use these.
and I have all the time that question in mind - "how US build up such an impressisve industry and stuff using measurment scale with its smallest unit commonly used is almost twice bigger than metrics smallest unit - a milimeter.. how one can do precise things with instruments having smallest details in 1/16 of inch.. and the whole idea of multiplying by 16 and not using equal values for base units.."
