I can feel the difference between 32F and -32F. Humans in the equatorial regions will never feel 0F but they will feel over 100F. Also, the humidity is a large component of how humans feel temperature as well. Heat indices are more accurate as to how humans sense temperature. But some people can’t stand cold temperatures that others can and vice versa with heat. Temperature is a scientific parameter and must be repeatable and standardized, not based on comfort level of disparate humans.
@@hearmeout9138 For most temperate regions, 0 F is about as cold as it gets, and 100 F about as warm as it gets. F is the way to go when reporting temperature or in casual discussion. The way it feels is in the numbers. No interpretation needed. For graphing changes in the earth's climate I'd rather Kelvin be used as that would more accurately reflect the magnitude of the change.
In fahrenheit: at 0 you're really cold, at 100 you're really hot. In Celcius: at 0 you're cold, at 100 you're dead. in Kelvin: at 0 you're dead, at 100 you're dead.
@@jds1275 it’s thrown off an astonishing amount. Even having taken college level chemistry and thermodynamics, I still had it set in my head that water boils at 212, period. Turns out where I live, it boils 15 degrees (F) lower than that. At the highest elevation I’ve boiled water for coffee, it’s a full 26 degrees difference. That’s 1/7th of the usual range between freezing and boiling!
Ah, so that's why C is a useless system, thank you for making it so easy to understand why, you forgot to say anything about conversion tho, 3:46 explains why Fahrenheit is much better
@@xp8969 My mom taught me that 28 years ago to help answer a possible question on some standardized test in high school (SATs? can't remember). And it worked! There was a question which that poem helped me answer correctly! But yes Fahrenheit is much better as explained in my other comment
Personally, I don't think that part matters about the body's core temperature because it can vary in humans by a few degrees Fahrenheit. I think however, it just works better from a standpoint of knowing when your feverish 100, is close to the upper limit of what humans can handle.
Actually... [insert ackchyually meme here] Fahrenheit intended for normal human body temp to be 90... and then 96. Fahrenheit based his model on an older model (Romer Scale) that has brine freeze at 0, water freeze at 7.5 and body temp at 22.5. Fahrenheit started by multiplying that scale by 4 to give more fine-grain detail and eliminate fractions. This put temps at those three temps at 0/30/90. Then he tweaked the scale up slightly to make it 0/32/96. This was done so that there was 64 degrees between freezing and human body temp. Why was this important? Because now you can easily mark degrees on your thermometer. Freeze water and mark your thermometer. Check your body temp and mark your thermometer. Now you have 32 and 96 recorded. Now mark the exact middle between those two marks. Now mark the exact middle between the three marks. Now mark the exact middle between those 5 marks... do this three more times and you've now got exact 1-degree Fahrenheit marks on your thermometer.
The Fahrenheit scale is the last thing I will give up in a metric dominated world. As you say 100 is hot, 0 is cold, it's a range within human experience.
Fahrenheit is also a finer scale. You can say 71F, but you would never say 21.67 C. You would have to say 21C or 22C, which would be actually closer to 70F and 72F. But really it is 71F you are trying to describe.
@stevemarvin will it depends on how precise you want to be. It's possible you heard it on TV say if it was from a weather station maybe I don't know... I'm just saying that in normal conversation people are not that precise.
Metric is better than imperial for doing calculations and conversions, but if you're doing manual work there can be benefits to using using like feet and inches with divisions of 12 because it divides evenly more ways than 10 does. (1, 2, 3, 4, and 6 versus 1, 2, 5, and 10.) It's the same reason that our time system is not based on 10s. You can use more simple numbers without using decimals.
Yeah it’s no accident, they chose 12 inches to the foot. It’s an easy thing to divide in half and thirds and in quarters. Doing that for 10 is not pretty especially not thirds.
Exactly! Same with 5280 feet in 1 mile. I think it was chosen that way because 5280 has so many different divisors, that the mile could easily be subdivided into halves, thirds, quarters, fifths, sixths, etc.
Except when using tools like sockets - Metric has no in between sizes. If 10mm is too small, try 11mm. In inches, how finely are you dividing the fraction? 1/8 or 7/16 or 5/32? I have on occasion had to go purchase an additional socket as it was in /32 instead of /16 or /8.
If you are doing sloppy Manual work sure count in feet, considering a human foot can vary from about 20 to more than 50cms in sizes good luck with that.
0°C being the temperature that water freezes at is the best feature of the Celsius scale. As someone who lives in an area that yo-yos above and below that line, I can tell you that transitioning from above to below 0°C is the most drastic shift in conditions. So much so, that it deserves to be the point that every other temperature is measured as above or below it. This is the temperature where rain falls instead as snow, and where wet roads turn into sheets of ice. Seeing the forecast of rain during the day, then falling to a low of -2°, instantly prepares me for what to expect having crossed that threshold.
I live in an area where the temp plunge well below 0°F and in summer will reach the low 100's. Zero Celsius (32°F) is a largely meaningless number. It's just a warm January day. Nothing really important happens, except that you might need to scrape your windows. Even the roads don't get icy at that point, because the we start dumping salt. Zero *Fahrenheit*, however, is very significant. It's when temps get dangerously cold, and--importantly--when roads actually get dangerously icy because salt brine becomes ineffective.
@@michaelwald6671"we start dumping salt" is the meaning. Despite that, it probably depends on how much downpour (soaking into the remaing snow, covering grid or washing away the salt) and how much yo-yo you have in the region.
@@michaelwald6671 sidewalks in cities do get icy and slippery already at -1°C (at least where i live they do) ... and having to scrape your windows in the morning or not might make quite the difference in when you have to leave the house i imagine
Canadian here. I was born in 1953 and we switched to metric in 1977 (when I was 24) so I’m fluent in Fahrenheit and Celsius. As a practical matter they’re pretty much the same. If you say the temperature is going to be 70F (in the U.S.) or 20C anywhere else, everyone knows you don’t need a coat.
I used F only my entire life (I'm 60) but in the last couple of years I started to embrace becoming Celsius 'fluent,' because I have a buddy in another country whom I chat with regularly. And we're always talking about the weather in our respective locations so I've made the habit of communicating it in C, so now I'm getting pretty comfortable with it. And as for all other metric measurements being superior, absolutely. I never could multiply fractions (etc) as a kid or adult and metric has been saving my butt for years in that regard lol. When old codgers complain about metric being "too complicated," I explain that our systems, if applied to money, a dollar would be 132 cents (as in ounces per gallon) and then some will see the light!
It's a bit of a misnomer to say Celsius is not used in science, I use it several times per day at work. Granted I work in water chemistry. I do find it useful to know how close my baths are to phase change transitions. That being said I have an excellent understanding of how hot water is at 60 C. You tell me it 32 C outside and I'm completely confused.
And the increments are identical in Kelvin and °C, only the offset differs by 273. So, if you need a temperature difference it's the same, no matter which scale.
This is amazing! I've never considered this. I think the value of this video is not in its debate about F vs C but in the illumination of how arbitrary both scales are! Thanks for the perspective Kyle. We nerds should all start using Kelvin in everyday talk. "Wow, should be over 300 this weekend. Lets plan a beach day!" "Hey guys, the temps haven't been over 270 in over a month! The ice has to be good to go. Lets get a hockey game together soon." Where my Dvorak users at? Ya'll down to convert to K?
IIRC, Fahrenheit himself (A GERMAN, not British OR American!) wanted 100 degrees to be the normal human temperature, since it's 98.6 F- He was damn close. Fahrenheit is the HUMAN relatable scale. Also, I remember when Celsius was called Centigrade and Kilohertz was called kilocycles. Then one day they changed, and no one told me. Yes, I'm old. LOL.
its not human relatable, its like caveman relatable. cooking revolves around boiling water, so actually on a practical level for everything EXCEPT WEATHER, celsius works better. and celsius isnt even bad for weather, because 0 celsius is a good point for snow.
This is why they say if your temperature is 100 or greater, you have a fever. There actually is some variation though slight with humans with their core temperature. So it technically is still a human scale from that standpoint. Personally, I kind of always wish we had had some sort of hybrid. Between Celsius and Fahrenheit. I prefer everything above freezing with Fahrenheit. But I do like that 0°c when it comes to freezing. Although it is interesting I think 0° f. Is the same as what a freezer should be. It would just be nice if they hit some kind of rounded numbers.
Pedantic nit picking here: The US has never used the "Imperial" system. The US Customary System is based on the PRE Imperial British system and thus the USCS is older than "Imperial" The difference is usually seen in VOLUME measures: Imperial pint is 20 Fluid ounces, USCS pint is 16 Fluid ounces for example. But overall, I use metric and USCS in most uses metric IS superior EXCEPT for weather reporting, Fahrenheit is a HUMAN scale: 0 degrees is to damn cold, 100 degrees is too damn hot. But hey, Give someone an inch and they'll take 1.61 kilometers. LOL
I like the more obvious thing where the point at which water turns into a dangerous slippery surface that you could contribute to a fall or sliding your car off the road being negative to be superior.
@jag92949 Celsius is a waste. Its never 100 C outside anywhere but in many places it can get to 100 F. Celsius also overuses the minus sign. When I think negative temperatures, it should be Arctic levels of cold, not just barely cold for snow
Oh the irony of Americans trying to tell us that 0 to 100, which is used only scale use in metric for every other measurement, rather than arbitrary numbers for inches to a foot, feet to a mile ounces to a pound, fluid ounces to a gallon 😝
OOO this will be a divisive one lol. Before watching, I'll say I agree with Kyle. The human body can detect a change in 1 degree with Fahrenheit. 0 degrees is cold as balls and 100 is hot as balls. It's much more intuitive than Celsius.
Yea. Also if you tell me, its in the 40s Fahrenheit outside I know what to expect and what to wear If you tell me its in the 20s Celsius, that can range from moderately cool to beach weather. Fahrenheit is way better for precision
@@buglepong I'm from the north, so on the rare 100 F days here, it's really, really uncomfortable to me. Maybe not "hot as balls" but certainly hot as ass 😅 Plus I can always put on more clothes but I can only get so naked lol
Thanks Geo Guy. I'm in a scientific field professionally with an advanced science degree. I understand the use of K and C in engineering, science (in general), and architecture. And I agree metrics are more accurate and useful even in daily usage (although I still prefer knowing the imperial lengths and so on; it's very simple to get an approximation of KM to mile so no big deal for me. Just personal preference. But now you've given me a good defense against my Celsius snob friends that stands up in practical terms. I'd never try to use F in a laboratory but....heck as far as "How's the weather today?" I surely can proudly say it's going to get up to 80F and not feel like I need to defend myself!
Not to be contrarian because I love your channel, Kyle. But, this is just my personal experience: As a 60-year-old American, I have found myself using Celsius a lot lately because I have been traveling overseas more and watching more RUclips videos by non-Americans. As a result, I am getting more accustomed to Celsius and I agree with other commenters who use both systems that the supposed human comfort scale really doesn’t matter that much in what system is used. It’s just what you're familiar with. Anyway, my physical Fahrenheit comfort range is about 30 to 90 and not 0 to 100. There is no magical difference between 100 and 101. The only thing I’ve noticed is that my nostrils tend to freeze at around 0 and driving on paved roads starts to get scary at 32. So, for me, I think of the Celsius comfort range as about -10 to 35, and the roads get scary at 0. Not really all that difficult. Maybe, we should just all use Kelvin and forget about these other systems.
THanKS for the great and detailed description of Fahrenheit. I've always liked it better than celsius because C requires using decimal points more often.
I love the fahrenheit scale, it's the primary unit of measure that I firmly believe is superior in Imperial than Metric. All because humans can easily relate. 0=very cold, 100=very hot. 78, perfect
And 50 makes sense being the middle, because it’s an awkward temp that can feel cold or warm depending on weather conditions and what season you’re in.
I heard it was developed on the basis that 0ºF was the temperature where meat and other perishable food could be safely stored long term, and 100ºF was the best estimate at the time of normal human body temperature.
I completely agree that metric is superior, with the one exception being Fahrenheit, which I actually love! I swear you are just like me. Just one correction. We use the US Customary System, not the Imperial System. It always bugged me when people called the US Customary system "Imperial." Great video!
Well Kyle as a 73 yr. old Canadian I am obviously very familiar with Celsius and Fahrenheit ( and Kelvin for that matter ) since we used the Imperial System until the mid 70's . But even in grade school in the 1950's I understood the Metric System since it was so basic even though I could not relate it to real life uses . Your point about Fahrenheit is interesting and the fact that each "degree" is less of an actual increase in heat makes it more accurate in whole degrees One thing that always puzzled me is " why 32 and 212 ? Why not 25 & 200 , or 50 & 250 ? Or if you contend that boiling point is not relatable then make freezing 100 degrees or better still make freezing " 0 " and so called room temperature " 100 " .
I find it easy to take a "ladder" method to manage C vs F. By that I mean memorizing a handful of pairs: 0C = 32F, 10C = 50F, 20C = 68F, 30C = 86F, 40C = 104F. When I see a temperature I can see which "rungs of the ladder" it falls between. Noticing that each increment of 10C = 18F led me to this method also.
You're just simply proving that you grew up in the USA. Over my life, I had to work with both the Celsius and Fahrenheit scales. One is simply a linear projection (line upon line) upon the other. And for what its worth, the Kelvin scale is a Celsius scale where the scale is simply shifted to take into account absolute zero, the lowest possible temperature. Kelvin = Celsius + 273.15 degrees. On the Celsius scale, if the weatherman tells me that this morning's low is going to be around 0 degrees C, I might expect a bit of frost. If the forecast high for that day is 10C, it's going to be nippy and I'll want to wear a jacket, if I go out. A forecast high of 20 degrees is going to be a pleasant spring day, shirt sleeve weather. A forecast high of 30 degrees means that it's going to be rather warm, like a day in late spring or early summer. A forecast high of 40 implies that it's going to he HOT (104 degrees F). It's all a matter of scale. An easy way to convert a Celsius temperature to Fahrenheit in your head goes like this. Double the Celsius temperature and subtract 10% from the result. Round down to the nearest whole number. Add 32 (30 + 2), if adding stepwise is easier for you.
This. 1 degree K = 1 degree C =1.8 degree F; it's only the zero point that changes between the C and the K, 0C being set to the freezing of water, 0K to the theoretical absolute zero where all molecular motion ceases. There are 100 degrees K between the freezing point and the boiling point of water at sea level.
I agree, metric is best. As for the “sciences” or “hard science” using Kelvin vs C that’s a pretty narrow niche. I work in the medical industry and everything we do is in C. I switched to C a few years ago and got used to it pretty quickly. I pretty much think in C now.
I disagree! Celsius is great, you get to work around the zero and the 100 which is practical. I wouldn’t say water freezing and boiling are only scientific things, they serve a purpose in your everyday life too. Temperature below zero means that the car should have winter tires, the kids should have padded clothes, main water connectors that aren’t in use during winter should be turned off etc. Temperature above 100 means that bacteria dies, the oil temperature in your car is ok, your sauna is too hot etc.
Naa. People think writing inch fractions as vulgar fractions mostly nonesensical. Decimal fractions are fine. E.g. 0.125 inch = 125 minch would be magnificent.
It's entirely up to what you're used to. To me and I'm sure 90% of other Celsius users would agree, that Celsius feels intuitive. 18 degrees sounds normal. 35 degrees sounds unbearably hot. And 6 degrees sounds very cold. The same way you say that we "already know it" because 0-100 farenhieght roughly describes a normal range of temperatures. I would suggest that Americas "already know Celsius" it's the same thing but (climate dependent) the normal range of temperatures is 0-40. It's no less intuitive than farenhieght. The only advantage I suppose is that you can be more granular since the range of normal temperatures is wider you can be more specific, which is helpful in getting a more accurate idea of the temperature when humidity, sun and wind have such a strong effect on how a given temperature actually feels.
The only reason we prefer Fahrenheit in this country is that we're used to it. Celsius is fine, but it's not something we grew up with. In Europe, it's the opposite. We know that 100°F is very hot; in Europe, they know that 40°C is very hot. Six of one and half a dozen of the other.
Celsius and Fahrenheit both have their advantages. I grew up with Celsius but have a working understanding of Fahrenheit due to some time spent in the USA. In my opinion the Fahrenheit vs Celsius debate is just needless polemic .... Mmetric vs imperial would be a much better topic. Not because imperial is bad, it isn't! But metric is much more pragmatic. It saves so much time and worries when you have to convert or scale.
I drive a German car, and I feel Celsius is better for understanding the temp gauge in the car. You know right away 100 in boiling, so any temp over 100 your relying on the cooling system to hold more pressure as the water in the system is wanting to undergo a phase change. With proper coolant the boiling point can be raised, which is why the temp gauge red line is at 110-120. But even if you put straight water in your car you can understand pretty easily that 100+ is pushing your luck.
I'm from Brazil and I'm used to Celcius. If you tell me it's 25 degrees outside, I'll take a T-shirt and get ready to a comfortable afternoon in Summer Clothes. The feeling that I have in my mind when I read 25 ºC is the same feeling you, Americans have when you read 77 ºF. It's only a matter of using it and get used to it.
I'm from Alaska and I'm used to Farenheit. If you tell me it's 25 degrees outside, I'll take a T-shirt and get ready to a comfortable afternoon in summer clothes. The feeling that I have in my mind when I read 25 F is the same feeling you Brazilians have when you read 25 C because Alaska is just that much cooler. Disclaimer I'm not actually Alaskan. But they would feel that way.
This is one of my hot takes. I believe Metric is superior in every use except temperature. Fahrenheit has a wider range, but its not so wide to where its unusable for day-to-day use like Kelvin.
Totally agree. I’m good at numbers and I could do the calculations but I can never recall the equation to multiply because I rarely need to. Being used to feet and inches is one thing but the simplicity of metric measurements is hard to argue against.
As a US-ian traveling through parts of Ontario and Quebec in September 1989, I saw the weather report my first morning in Canada and was _freaked_ to hear the meteorologist to casually say the high will be 25 today. I checked and found that was about 75 to my U.S. ears. It was a beautiful day!
You're explaining very well what I've tried to tell people. Once I was traveling through Canada and I saw a national TV weather forecast while I was there. The high temps on the map ranged from 19 in Whitehorse and Yellowknife to 23 in Toronto and Montreal. Not much variance on the scale! Also, you can dial in the temperature you want in modern cars. If you choose the Fahrenheit scale, it goes up one number at a time: 66, 67, 68, 69, 70, 71, 72, 73. If you choose the Celsius scale, the jumps are too big from one number to the next, so it goes up half a degree at a time: 18.5. 19.0, 19.5, 20.0, 20.5. After those two experiences, I came to the conclusion that Fahrenheit is better for everyday usage.
I like the Imperial system of lengths when it comes to measuring with body parts. I use the width of my thumbs to measure in inches, and my feet to measure, well feet, and a outstretched arm or a large step to measure a yard (that works for meters as well). Sometimes you don't have a tape measure and it's really useful to be able to estimate the dimensions of a room or garden plot or whatever.
I saw the title and I figure correctly what Kyle was going to say. I agree. I put everything in Celsius - my thermostats, phone apps, smart watch for about a year. I'm now quite comfortable with Celsius for everyday use. That is if you tell me it's 28 C outside, I don't have to convert to Fahrenheit to know that's a pleasant but just a little warm temperature. But, mostly due to conversing with other Americans using F, I switched everything to F. I like it better because as Kyle says 0 to 100, cold to hot for air temperature. Nice we can say over 100 to mean really hot and below 0 to say really cold.
I'm gonna be the european in the room and try to disprove your point, so here goes: 1. 'Fahrenheit is better for the common man'. I think that's totally based on personal opinion. People who use Celsius generally know that 0 is (literally) freezing. 10 is coldish. 20 is cool. 30 is hot and 40 is too hot. It makes intuitive sense to us just like the 25,50,75,100 system makes sense to you. I think you (and I about celsius) just feel like these systems make sense because we grew up with it. A totally different system with other numbers would probably also make sense to us if we grew up with it. It's purely personal opinion. And if you think that Fahrenheit is still more a system for the common man than Celsius 'because very cold = 0 and very hot = 100 just makes intuitive sense', it doesn't really make sense that freezing = 32 right? For me it makes sense that 0 = freezing, because I grew up seeing that on the news and knowing that there would be snow/ice on the ground, meaning I needed to be more careful biking everywhere. That feels like a really clean round number to me. Do you see that it's just a matter of opinion? It's really just about what you like more. The one thing that Fahrenheit does kind of do better is that it's a smaller unit of measurement than celsius, which could be nice to know when you need to choose what to wear to match the temperature for example, but in my experience this isn't an issue for me as someone who only uses celsius. 2. The benefit of Celsius: There is really only one thing that differenciates Celsius from Fahrenheit and that is how much more scientifically relevant Celsius is. If I remember correctly you said that that wasn't relevant because Kelvin is used for scientific calculations anyways. Even though that's right, that doesn't change that (simplified) Kelvin is just a version of Celsius that has a lower starting point (To show you, these are some values of Kelvin(K) and Celsius(C) next to each other: K=0 = C=-273, K=273 = C=0, K=373 = C=100). This made Kelvin very easy for me to learn as a child, because it was just -273 of anything I knew already. Kelvin isn't as easy for someone who grows up with Fahrenheit. So logically someone who doesn't grow up with celsius probably makes more mistakes using Kelvin. Which means that you could argue that growing up with Fahrenheit is disadvantageous for these people if they want to enter the scientific field. Since this is the only thing that truely differenciates Celsius from Fahrenheit aside from personal preference, I hereby declare that Celcius is better than Fahrenheit! For me this is just a fun brain exercise. Please prove me wrong if you can, hope this was good food for thought!
The term "Freedom units" is actually ironic. We use the system we got from the very nation we went to war against to gain our freedom, WORSE the Metric system was invented by France, The nation that HELPED us gain said freedom. So in REALITY, Metric IS the "freedom units". Also Fahrenheit is neither English or French, We got Fahrenheit from the GERMANS.
I tell my Canadian relatives this exact idea all the time. They are reluctant converts to the metric system as is, still preferring to use imperial measurements for things like height, weight and short distances. But they have completely bought in on the centigrade scale for temps. They spend half the year living in below zero temperatures because of this now.
A few F-to-C correspondences are easy to remember: 32 F = 0 C (water freezes, snow becomes possible) 68 F = 20 C (typical indoor thermostat setting in the US) and from those you can derive one more landmark temperature: 50 F = 10 C (sweater weather)
As a Canadian, I feel that feet, inches, pounds are generally superior to the metric system. Most Canadians use these for heights and weights. Most don't even know their heights in cm or weights in kg because the metric system stinks there.
Sorry Kyle but using the 'common man' usage is a pretty flimsy argument for me! If you've grown up in Europe the you just know if it's 35C then it's going to be a sweltering day and likewise if they say it's going to be 5C then you know to crank up the heating and put a sweater on under your cost when you go out.
The reason given in effect is only that Fahrenheit is better for US citizens because they're familiar with it. In short: continue using what you're accustomed to (which is fine of course). Neither valid pros nor cons given.
I think what Kyle is saying is that it’s designed for common man. I know people are used to it but people can get used to almost anything. 0-100 makes more sense from a design perspective. 0 - 40 does not.
@@jeffwatson7315 Not only a 0 to 100 scale more intuitive than a 0 to 40 scale, the 0 to 40 scale also doesn't cover the habitable environment as well; at 0 degree Celsius you don't even see snow.
It is easy to convert Celsius to kelvin, just add absolute temperature that is 273.15. Celsius is highly logical, Zero means freezing, 18 to 25 is pleasant, 30+ is hot 35+ very hot, 40+is heat wave. For. Those living in a tropical region, Celsius is the best. Fahrenheit has many range, that human doesnot need. We just need, is it freezing , boiling, at what pressure (cooking). Sorry, I will take Celsius
I agree completely! As an American, I wish were used the metric system. However, Fahrenheit is better for the reasons stated and should be kept. the thing about temperatures compared to the other forms of measurement is that temperature is linear, we never have to convert temperatures within a scale unlike figuring out how many inches are in a mile or centimeters in a kilometer (of course that one is easy). A temperature just is and you only need to convert when jumping from one system to the other. Great explanation about these systems. Another thing about the freezing and boiling points; Those only work if you're at sea level. If you're up at altitude water boils at a lower temperature because there's less atmospheric pressure which also impacts when water boils. Anyone who lives in mountain areas already knows that cooking times are slightly longer because of this.
Agreed about no conversion within one system. However, usually you buy the themometer labelled with he scale -- If you have to do it, only needing pure water under certain conditions would still be easier to reproduce than saltwater under certsin conditions plus "the average body without fever".
Kyle, I gotta admit I was skeptical of the title...totally NOT click bait! You're right, and I never even knew how convenient fahrenheit is, as an American!! Big props and thanks for another great video!!!
Total BS. The only reason he states the F is better is because he grew up with it and used to it. The only difference between two I’d the starting point. How often in life you will use absolute zero degrees?
It's the exact opposite. You only think Celsius is better because you are familiar with it. Also, absolute zero is necessary for scientific calculations.
You’re completely right, as a scientist Kelvin is clearly the better system for chemical and physical calculations and 0-100 F is a physically relevant range for human experience. 0 C is irrelevant because it doesn't even guarantee you see frozen precipitation, usually it has to be colder than that for the snow to stick around at all, and 100 C is a bad time if you are personally experiencing it.
I've been saying this for years! Farenheit for weather, Celsius for cooking! Also I agree the metric system is largely superior, but it's biggest weakness in my opinion is that it lacks a unit measurement for the length of about 1 foot. It's such a convenient unit length to have as there are so many things that aren't nearly a meter but are way longer than a centimeter
How frequently you need it depends what you are doing. On which depends the required precision. Possibly: 1 ft ~ 30 cm ~ 1/3 m 2 ft ~ 60 cm > 1/2 m (roughly of course, else you wouldn't miss feet anyways) If you're not accustomed to foot, you don't actually miss it, my personal experience.
In order to convert from C. to F., all you have to do is know 4 numbers and interpolate: -40 C = -40 F 0 C = 32 F 23 C = 73 F 40 C = 104 F Most everything in the external temperature range, which constitutes most people's experience, lies between those numbers. Even for temps above 104 F you can extrapolate.
@@GeographyKing Ehhh, my coworkers who grew up abroad have a great intuitive understanding of celsius and no clue about Fahrenheit. It's intuitive to me and not at all to them.
When Fahrenheit found his scale he based it on the temperature at which seawater froze. That became zero degrees. He set a mark for the freezing of fresh water, which he found at 32. To set the temperature of the 'opposite' of freezing: boiling. On a circle, opposites are 180 degrees apart. 32 degrees (freezing) and 212 degrees (boiling) put his scale in that 'human experience' zone which you describe. As another comments here, it is the scale that humans feel/experience.
The way I see it, the crux of the argument is largely, "Fahrenheit is what I'm familiar with, so it makes more sense to me" -- the same thing my high school students would say about Celsius. When you're in a place that often sees temperatures just above or just below freezing, Celsius is a HUGE advantage: -1, the road could be icy, +1 and you're probably fine. You don't have to be that familiar with the scale to know what it represents, you know that negative numbers mean slippery surfaces. But to the first point... if you grew up with Celsius -- which I didn't, as I grew up near Detroit on the Canadian side and we always watched American newscasts in Fahrenheit -- that's going to just seem more natural to you. A hot summer day is 30 and above; a cold winter night is -20 (or, if you're in Saskatoon, -40). So on those grounds it's a matter of taste -- but as someone who's fully converted to Celsius for everyday use, I can assure you that I'm at no disadvantage because, say, Fahrenheit is a finer-grained system (it's irrelevant most of the time). If you're trying to make an argument on "human experience" grounds... some people find 40 F unbearably cold, and some (like me) find 90 F unbearably hot. Humans have a wide range of experiences and sentiments, but basing a temperature scale on the cold sterility and unwavering (mostly) properties of water, that's just good sense. In conclusion, the imperial system is just stupid and it all needs to go. Those NASA scientists that forgot to convert one thing from imperial to metric and lost a multi-hundred-million-dollar Mars mission... none of that would've happened if the US had the guts to fully commit to metric in the '70s like they promised they would. Plus, basing the length of something on the king's actual foot? Madness. And finally... because the US is so close to us, and so dominant, they are effectively preventing Canada from becoming as metric as we should be. I know my height in feet and inches better than in centimetres, and that's just not right.
I live in Minnesota which frequently gets below freezing and usually stays below freezing most of the winter. Its not hard to remember 32 F. It really isnt.
Roads don't usually get icy at 32°, because most places with real winters will dump salt and brine on the roads. Salt becomes ineffective at--you guessed it--Zero degrees Fahrenheit.
@michaelwald6671 Also roads arent gonna freeze right away lol Its not like it drops from 33 to 32 and all of a sudden, a puddle of water is a sheet of ice. It also wont make a perfectly dry surface become icy.
I've argued this for years. We don't base our lives on the boiling point of water at sea level. However, measuring distance, the metric is far superior.
The only time my life is really dependent on a Thermometer is if I need to know the severity of a fever. For weather they could use words instead of temperature. For my barh or tea I just feel it So, precise measurement is needed for orher things, like the washing machine, car coolant...
Sigh. This old saw. "50 being right in the middle is not going to be either hot nor cold, it's going to be pretty mild." This is not true for anyone brought up in a temperate climate. 70°F is comfortable for a normal person. 50°F would be at least sweater weather for the average person. 75°F would be still be comfortable, not warm, to most people. 100°F would be heat warnings in most places. 0°F would be "you will die without proper equipment" in most places. 32°F is the freezing point of water and very, not kinda, cold. If you want a glimpse into madness, go lookup the actual reasons for the specific 0°F and, well, other measurements of the Fahrenheit scale (there is no specific reason for its 100°F as far as I could find). It's completely arbitrary lunacy that doesn't seem to even have a consistent explanation, other than being consistently bizarre. I live in the US and use Fahrenheit regularly but I don't go around trying to justify it.
@@GeographyKing You literally just made a video justifying the Fahrenheit scale. I'm not making this a "my system's better than your system" debate. I didn't defend any particular scale in my comment. Use whatever system you want. But, the Fahrenheit scale is absolutely not a scale for humans. Like I said, I mostly use the Fahrenheit scale but I don't defend it because it's not any better than any other scale and there are clear drawbacks. And, seriously, read the wiki page on how the Fahrenheit scale was calibrated. I defy you to claim it's a rational system after reading its history. Its multiple choice history.
As an engineering student, if I'm given a problem where temperature is a factor, Celsius is a lot easier to work with and what I'll always prefer. If I need to know what to wear, I'm using Fahrenheit because it makes intuitive sense, the 0 to 100 portion tells me how comfortable it is, anything above or below that tells me how much faster I'm gonna die outside.
Agreed! I have been saying this for years. Americans should probably switch to metric for everything else, but the rest of the world should really get on the Fahrenheit train.
America is metric officially, but the federal government has no authority to force people to use it outside if the FDA. Which is why all food and drugs must be labeled in MKS
The pneumonic I learned for Celsius is: 30 is hot, 20 is nice, 10 is cool and 0 is ice. For me this is just a way to understand temperature maps in Europe, Asia, etc... so when you travel you can kinda understand the weather forecast and understand why upper 30s and 40s in the UK last year was so unbearable.
Growing up in Canada I always liked the symmetry of Celsius: about half the year is above 0 and half is below. The distance from 0 tells you how warm or cold it is. The 0-100 idea with Fahrenheit is nice, except for the fact that certain areas routinely see temperatures outside this range. Ultimately I think it’s a toss up.
My thoughts exactly. As a Canadian I grew up with F. and stick with it even after the country went metric. Prefer metric in everything except temp. for all the reasons outlined by G.K.
including number of days in a month. What a rubbish! Try moving out of your apartment on the 5th of a month. Landlord will prorate your rent differently in February vs March.
@@chefnycThat's why I don't rent, I own. I pay my monthly mortgage 12 times a year, don't care about the number of days each month. And my equity grows every year, so if I move, I just sell for a large profit. If I don't sell, nothing changes except for yearly increases in homeowners insurance & sometimes property taxes, always more than offset by continued growing equity. Win-win... oh, and a mortgage is cheaper than rent even during inflation. Paying rent is insane, a money pit, a losing proposition. Always own, never rent.
Even my Canadian friends begrudgingly admit that 100F conveys a more accurate feeling than 38C (or whatever the conversion is). And who really thinks 19C is a nice day? Nerds. That's who. 75F is way more obviously a nice day.
American, here. Celsius is better than Fahrenheit when it comes to doing math and science. Its obviously not as good as kelvin, but it’s on the same scale as kelvin. In order to convert from Celsius to kelvin, all you have to do is add 3 hundred something, I forgot the exact number. So all the math is the same, just have to add that bit in the beginning. Also, as someone else mentioned, Celsius is useful for dealing with water. We deal with water when we cook. 0 and 100 are easy to remember, 0 for freezing/melting and 100 for boiling/condensing.
Kelvin describes how atoms feel. Celsius describes how water feels. Fahrenheit describes how humans feel.
Actually, Fahrenheit describes how saltwater and a horse feel.
@@jeremycraft8452 actually no
I can feel the difference between 32F and -32F. Humans in the equatorial regions will never feel 0F but they will feel over 100F. Also, the humidity is a large component of how humans feel temperature as well. Heat indices are more accurate as to how humans sense temperature. But some people can’t stand cold temperatures that others can and vice versa with heat. Temperature is a scientific parameter and must be repeatable and standardized, not based on comfort level of disparate humans.
@@hearmeout9138huh
@@hearmeout9138 For most temperate regions, 0 F is about as cold as it gets, and 100 F about as warm as it gets. F is the way to go when reporting temperature or in casual discussion. The way it feels is in the numbers. No interpretation needed.
For graphing changes in the earth's climate I'd rather Kelvin be used as that would more accurately reflect the magnitude of the change.

Fahrenheit is for people, Celsius is for water. As a people i approve of this message.
It's for water until you change your altitude. Then the scale is thrown off a bit.
@@jds1275 it’s thrown off an astonishing amount. Even having taken college level chemistry and thermodynamics, I still had it set in my head that water boils at 212, period. Turns out where I live, it boils 15 degrees (F) lower than that. At the highest elevation I’ve boiled water for coffee, it’s a full 26 degrees difference. That’s 1/7th of the usual range between freezing and boiling!
As seventy percent water, I approve of Celsius.

People are 60% water.
So, Fahrenheit is only for the 40% of the other stuff that makes up a body/person.

How is - 40 good news? It can easily kill you. I guess if you love danger that's good. To each his own.
Of course Mr. Fahrenheit meant for 100 to be the average human body temperature but was a bit off due to a rounding error.
Personally, I don't think that part matters about the body's core temperature because it can vary in humans by a few degrees Fahrenheit. I think however, it just works better from a standpoint of knowing when your feverish 100, is close to the upper limit of what humans can handle.
Actually... [insert ackchyually meme here]
Fahrenheit intended for normal human body temp to be 90... and then 96. Fahrenheit based his model on an older model (Romer Scale) that has brine freeze at 0, water freeze at 7.5 and body temp at 22.5. Fahrenheit started by multiplying that scale by 4 to give more fine-grain detail and eliminate fractions. This put temps at those three temps at 0/30/90.
Then he tweaked the scale up slightly to make it 0/32/96. This was done so that there was 64 degrees between freezing and human body temp. Why was this important? Because now you can easily mark degrees on your thermometer. Freeze water and mark your thermometer. Check your body temp and mark your thermometer. Now you have 32 and 96 recorded.
Now mark the exact middle between those two marks. Now mark the exact middle between the three marks. Now mark the exact middle between those 5 marks... do this three more times and you've now got exact 1-degree Fahrenheit marks on your thermometer.
And zero in Fahrenheit is when saltwater freezes. So, there is a reason for the range.
@@gregm766 Saltwater freezes at approximately 28.4 degrees Fahrenheit.
@@mournblade1066 I stand corrected. I was given faulty infromation.
The Fahrenheit scale is the last thing I will give up in a metric dominated world. As you say 100 is hot, 0 is cold, it's a range within human experience.
The range goes beyond in both directions.
Sometime, you might want to measure sth else than your body ;)
It's not just a matter of hot and cold, 0c and 100c are the temperatures when water changes state from solid to liquid to gas
Fahrenheit is also a finer scale. You can say 71F, but you would never say 21.67 C. You would have to say 21C or 22C, which would be actually closer to 70F and 72F. But really it is 71F you are trying to describe.
To be fair, they probably would say 22.7 C. Which is still dumb, who wants decimals in their temps?
Exactly
@@stevemarvin I've never heard anybody in the UK use decimals when referring to the outside temperature.
@@desertodavid You may be right. I swear I saw it on either UK or German TV years ago but it could be a false memory. If so I stand corrected.
@stevemarvin will it depends on how precise you want to be. It's possible you heard it on TV say if it was from a weather station maybe I don't know... I'm just saying that in normal conversation people are not that precise.
This is a great explanation of why certain scales are better than others!
Metric is better than imperial for doing calculations and conversions, but if you're doing manual work there can be benefits to using using like feet and inches with divisions of 12 because it divides evenly more ways than 10 does. (1, 2, 3, 4, and 6 versus 1, 2, 5, and 10.) It's the same reason that our time system is not based on 10s. You can use more simple numbers without using decimals.
Yeah it’s no accident, they chose 12 inches to the foot. It’s an easy thing to divide in half and thirds and in quarters. Doing that for 10 is not pretty especially not thirds.
Exactly! Same with 5280 feet in 1 mile. I think it was chosen that way because 5280 has so many different divisors, that the mile could easily be subdivided into halves, thirds, quarters, fifths, sixths, etc.
I do wish the imperial length system went one more unit down because an inch is way too large of a unit, and the fractional inches are just messy.
Except when using tools like sockets - Metric has no in between sizes. If 10mm is too small, try 11mm. In inches, how finely are you dividing the fraction? 1/8 or 7/16 or 5/32? I have on occasion had to go purchase an additional socket as it was in /32 instead of /16 or /8.
If you are doing sloppy Manual work sure count in feet, considering a human foot can vary from about 20 to more than 50cms in sizes good luck with that.
0°C being the temperature that water freezes at is the best feature of the Celsius scale. As someone who lives in an area that yo-yos above and below that line, I can tell you that transitioning from above to below 0°C is the most drastic shift in conditions. So much so, that it deserves to be the point that every other temperature is measured as above or below it. This is the temperature where rain falls instead as snow, and where wet roads turn into sheets of ice. Seeing the forecast of rain during the day, then falling to a low of -2°, instantly prepares me for what to expect having crossed that threshold.
I live in an area where the temp plunge well below 0°F and in summer will reach the low 100's.
Zero Celsius (32°F) is a largely meaningless number. It's just a warm January day. Nothing really important happens, except that you might need to scrape your windows.
Even the roads don't get icy at that point, because the we start dumping salt.
Zero *Fahrenheit*, however, is very significant. It's when temps get dangerously cold, and--importantly--when roads actually get dangerously icy because salt brine becomes ineffective.
I mean sure but you can also just take the same philosophy for 32 degrees Fahrenheit
@@michaelwald6671"we start dumping salt" is the meaning.
Despite that, it probably depends on how much downpour (soaking into the remaing snow, covering grid or washing away the salt) and how much yo-yo you have in the region.

Canadian here. I was born in 1953 and we switched to metric in 1977 (when I was 24) so I’m fluent in Fahrenheit and Celsius. As a practical matter they’re pretty much the same. If you say the temperature is going to be 70F (in the U.S.) or 20C anywhere else, everyone knows you don’t need a coat.
With F we have the ease of saying "it'll be in the 70s". "In the 20s" in celcius is a range too broad to be meaningful

@@chuckinhouston9952 Instead of miles per gallon, they use how many liters per 100km's. No easy to make a quick conversion.
I used F only my entire life (I'm 60) but in the last couple of years I started to embrace becoming Celsius 'fluent,' because I have a buddy in another country whom I chat with regularly. And we're always talking about the weather in our respective locations so I've made the habit of communicating it in C, so now I'm getting pretty comfortable with it.
And as for all other metric measurements being superior, absolutely. I never could multiply fractions (etc) as a kid or adult and metric has been saving my butt for years in that regard lol. When old codgers complain about metric being "too complicated," I explain that our systems, if applied to money, a dollar would be 132 cents (as in ounces per gallon) and then some will see the light!
@@ReverendMeat51I’m fine with temps between 68°F and 85°F. There’s always a margin of error when predicting temperature.
It's a bit of a misnomer to say Celsius is not used in science, I use it several times per day at work. Granted I work in water chemistry. I do find it useful to know how close my baths are to phase change transitions. That being said I have an excellent understanding of how hot water is at 60 C. You tell me it 32 C outside and I'm completely confused.

Where my Dvorak users at? Ya'll down to convert to K?
IIRC, Fahrenheit himself (A GERMAN, not British OR American!) wanted 100 degrees to be the normal human temperature, since it's 98.6 F- He was damn close. Fahrenheit is the HUMAN relatable scale. Also, I remember when Celsius was called Centigrade and Kilohertz was called kilocycles. Then one day they changed, and no one told me. Yes, I'm old. LOL.

This is why they say if your temperature is 100 or greater, you have a fever. There actually is some variation though slight with humans with their core temperature. So it technically is still a human scale from that standpoint.
Personally, I kind of always wish we had had some sort of hybrid. Between Celsius and Fahrenheit. I prefer everything above freezing with Fahrenheit. But I do like that 0°c when it comes to freezing. Although it is interesting I think 0° f. Is the same as what a freezer should be. It would just be nice if they hit some kind of rounded numbers.

Just personal preference.
But now you've given me a good defense against my Celsius snob friends that stands up in practical terms. I'd never try to use F in a laboratory but....heck as far as "How's the weather today?" I surely can proudly say it's going to get up to 80F and not feel like I need to defend myself!
Not to be contrarian because I love your channel, Kyle. But, this is just my personal experience: As a 60-year-old American, I have found myself using Celsius a lot lately because I have been traveling overseas more and watching more RUclips videos by non-Americans. As a result, I am getting more accustomed to Celsius and I agree with other commenters who use both systems that the supposed human comfort scale really doesn’t matter that much in what system is used. It’s just what you're familiar with. Anyway, my physical Fahrenheit comfort range is about 30 to 90 and not 0 to 100. There is no magical difference between 100 and 101. The only thing I’ve noticed is that my nostrils tend to freeze at around 0 and driving on paved roads starts to get scary at 32. So, for me, I think of the Celsius comfort range as about -10 to 35, and the roads get scary at 0. Not really all that difficult.
Maybe, we should just all use Kelvin and forget about these other systems.
It's all arbitrary. "A rose by any other name would smell as sweet"
THanKS for the great and detailed description of Fahrenheit. I've always liked it better than celsius because C requires using decimal points more often.
I love the fahrenheit scale, it's the primary unit of measure that I firmly believe is superior in Imperial than Metric.
All because humans can easily relate. 0=very cold, 100=very hot. 78, perfect
32 is a popsicle, so 0 is way beyond very cold.
And 50 makes sense being the middle, because it’s an awkward temp that can feel cold or warm depending on weather conditions and what season you’re in.
50 should be perfect if Fahrenheit were a relatable system

Well Kyle as a 73 yr. old Canadian I am obviously very familiar with Celsius and Fahrenheit ( and Kelvin for that matter ) since we used the Imperial System until the mid 70's . But even in grade school in the 1950's I understood the Metric System since it was so basic even though I could not relate it to real life uses .
Your point about Fahrenheit is interesting and the fact that each "degree" is less of an actual increase in heat makes it more accurate in whole degrees
One thing that always puzzled me is " why 32 and 212 ? Why not 25 & 200 , or 50 & 250 ? Or if you contend that boiling point is not relatable then make freezing 100 degrees or better still make freezing " 0 " and so called room temperature " 100 " .
I find it easy to take a "ladder" method to manage C vs F. By that I mean memorizing a handful of pairs: 0C = 32F, 10C = 50F, 20C = 68F, 30C = 86F, 40C = 104F. When I see a temperature I can see which "rungs of the ladder" it falls between. Noticing that each increment of 10C = 18F led me to this method also.
You're just simply proving that you grew up in the USA. Over my life, I had to work with both the Celsius and Fahrenheit scales. One is simply a linear projection (line upon line) upon the other. And for what its worth, the Kelvin scale is a Celsius scale where the scale is simply shifted to take into account absolute zero, the lowest possible temperature. Kelvin = Celsius + 273.15 degrees.
On the Celsius scale, if the weatherman tells me that this morning's low is going to be around 0 degrees C, I might expect a bit of frost. If the forecast high for that day is 10C, it's going to be nippy and I'll want to wear a jacket, if I go out. A forecast high of 20 degrees is going to be a pleasant spring day, shirt sleeve weather. A forecast high of 30 degrees means that it's going to be rather warm, like a day in late spring or early summer. A forecast high of 40 implies that it's going to he HOT (104 degrees F). It's all a matter of scale.
An easy way to convert a Celsius temperature to Fahrenheit in your head goes like this.
Double the Celsius temperature and subtract 10% from the result. Round down to the nearest whole number. Add 32 (30 + 2), if adding stepwise is easier for you.
This.
1 degree K = 1 degree C =1.8 degree F; it's only the zero point that changes between the C and the K, 0C being set to the freezing of water, 0K to the theoretical absolute zero where all molecular motion ceases. There are 100 degrees K between the freezing point and the boiling point of water at sea level.
I agree, metric is best. As for the “sciences” or “hard science” using Kelvin vs C that’s a pretty narrow niche. I work in the medical industry and everything we do is in C. I switched to C a few years ago and got used to it pretty quickly. I pretty much think in C now.
It doesn’t really matter which one is better.
The fact is that about 7.5 billion people use Celsius and only about 500 million people use Fahrenheit.
Solid video Kyle, surprisingly interesting!
I disagree! Celsius is great, you get to work around the zero and the 100 which is practical. I wouldn’t say water freezing and boiling are only scientific things, they serve a purpose in your everyday life too.
Temperature below zero means that the car should have winter tires, the kids should have padded clothes, main water connectors that aren’t in use during winter should be turned off etc.
Temperature above 100 means that bacteria dies, the oil temperature in your car is ok, your sauna is too hot etc.
I'm not getting why sauna temperature would be practical for general use. I, and the vast majority of people on Earth, have never been in a sauna.
People think inch fractions are inferior to mm but then use decimal Celsius temperatures.
Naa. People think writing inch fractions as vulgar fractions mostly nonesensical. Decimal fractions are fine.
E.g. 0.125 inch = 125 minch would be magnificent.
It's entirely up to what you're used to. To me and I'm sure 90% of other Celsius users would agree, that Celsius feels intuitive.
18 degrees sounds normal. 35 degrees sounds unbearably hot. And 6 degrees sounds very cold.
The same way you say that we "already know it" because 0-100 farenhieght roughly describes a normal range of temperatures. I would suggest that Americas "already know Celsius" it's the same thing but (climate dependent) the normal range of temperatures is 0-40.
It's no less intuitive than farenhieght. The only advantage I suppose is that you can be more granular since the range of normal temperatures is wider you can be more specific, which is helpful in getting a more accurate idea of the temperature when humidity, sun and wind have such a strong effect on how a given temperature actually feels.
I like fahrenheit because it's more exact
The only reason we prefer Fahrenheit in this country is that we're used to it. Celsius is fine, but it's not something we grew up with. In Europe, it's the opposite. We know that 100°F is very hot; in Europe, they know that 40°C is very hot. Six of one and half a dozen of the other.
Fahrenheit is much more useful in setting a thermostat.
@@jerrymeadows5059 yes because youre used to it. For me who has grown up with celsius its easier with celsius
Celsius and Fahrenheit both have their advantages. I grew up with Celsius but have a working understanding of Fahrenheit due to some time spent in the USA.
In my opinion the Fahrenheit vs Celsius debate is just needless polemic ....
Mmetric vs imperial would be a much better topic. Not because imperial is bad, it isn't! But metric is much more pragmatic. It saves so much time and worries when you have to convert or scale.
you think he doesn't know that?
This is an interesting surprise. The geography of temperature!
Now here's a real challenge for you: defend the British system of weighing themselves via stone.
I drive a German car, and I feel Celsius is better for understanding the temp gauge in the car. You know right away 100 in boiling, so any temp over 100 your relying on the cooling system to hold more pressure as the water in the system is wanting to undergo a phase change. With proper coolant the boiling point can be raised, which is why the temp gauge red line is at 110-120. But even if you put straight water in your car you can understand pretty easily that 100+ is pushing your luck.

Good video once again King!
I'm from Brazil and I'm used to Celcius. If you tell me it's 25 degrees outside, I'll take a T-shirt and get ready to a comfortable afternoon in Summer Clothes. The feeling that I have in my mind when I read 25 ºC is the same feeling you, Americans have when you read 77 ºF. It's only a matter of using it and get used to it.
I'm from Alaska and I'm used to Farenheit. If you tell me it's 25 degrees outside, I'll take a T-shirt and get ready to a comfortable afternoon in summer clothes. The feeling that I have in my mind when I read 25 F is the same feeling you Brazilians have when you read 25 C because Alaska is just that much cooler.
Disclaimer I'm not actually Alaskan. But they would feel that way.
This is one of my hot takes. I believe Metric is superior in every use except temperature. Fahrenheit has a wider range, but its not so wide to where its unusable for day-to-day use like Kelvin.
Totally agree. I’m good at numbers and I could do the calculations but I can never recall the equation to multiply because I rarely need to. Being used to feet and inches is one thing but the simplicity of metric measurements is hard to argue against.
Celsius is better because it clearly says below zero is freezing. Easy for drivers. Otherwise it is where you were grown
As a US-ian traveling through parts of Ontario and Quebec in September 1989, I saw the weather report my first morning in Canada and was _freaked_ to hear the meteorologist to casually say the high will be 25 today. I checked and found that was about 75 to my U.S. ears. It was a beautiful day!
You're explaining very well what I've tried to tell people. Once I was traveling through Canada and I saw a national TV weather forecast while I was there. The high temps on the map ranged from 19 in Whitehorse and Yellowknife to 23 in Toronto and Montreal. Not much variance on the scale! Also, you can dial in the temperature you want in modern cars. If you choose the Fahrenheit scale, it goes up one number at a time: 66, 67, 68, 69, 70, 71, 72, 73. If you choose the Celsius scale, the jumps are too big from one number to the next, so it goes up half a degree at a time: 18.5. 19.0, 19.5, 20.0, 20.5. After those two experiences, I came to the conclusion that Fahrenheit is better for everyday usage.
I like the Imperial system of lengths when it comes to measuring with body parts. I use the width of my thumbs to measure in inches, and my feet to measure, well feet, and a outstretched arm or a large step to measure a yard (that works for meters as well). Sometimes you don't have a tape measure and it's really useful to be able to estimate the dimensions of a room or garden plot or whatever.
Completely agree. This is how imperial developed in the first place! To be able to approximate measurements based on real-life things.
Sometimes I don’t have the British King with me. So I don’t know what “1 foot” is.
I saw the title and I figure correctly what Kyle was going to say. I agree. I put everything in Celsius - my thermostats, phone apps, smart watch for about a year. I'm now quite comfortable with Celsius for everyday use. That is if you tell me it's 28 C outside, I don't have to convert to Fahrenheit to know that's a pleasant but just a little warm temperature.
But, mostly due to conversing with other Americans using F, I switched everything to F. I like it better because as Kyle says 0 to 100, cold to hot for air temperature. Nice we can say over 100 to mean really hot and below 0 to say really cold.
I'm gonna be the european in the room and try to disprove your point, so here goes:
1. 'Fahrenheit is better for the common man'. I think that's totally based on personal opinion. People who use Celsius generally know that 0 is (literally) freezing. 10 is coldish. 20 is cool. 30 is hot and 40 is too hot. It makes intuitive sense to us just like the 25,50,75,100 system makes sense to you. I think you (and I about celsius) just feel like these systems make sense because we grew up with it. A totally different system with other numbers would probably also make sense to us if we grew up with it. It's purely personal opinion. And if you think that Fahrenheit is still more a system for the common man than Celsius 'because very cold = 0 and very hot = 100 just makes intuitive sense', it doesn't really make sense that freezing = 32 right? For me it makes sense that 0 = freezing, because I grew up seeing that on the news and knowing that there would be snow/ice on the ground, meaning I needed to be more careful biking everywhere. That feels like a really clean round number to me. Do you see that it's just a matter of opinion? It's really just about what you like more. The one thing that Fahrenheit does kind of do better is that it's a smaller unit of measurement than celsius, which could be nice to know when you need to choose what to wear to match the temperature for example, but in my experience this isn't an issue for me as someone who only uses celsius.
2. The benefit of Celsius: There is really only one thing that differenciates Celsius from Fahrenheit and that is how much more scientifically relevant Celsius is. If I remember correctly you said that that wasn't relevant because Kelvin is used for scientific calculations anyways. Even though that's right, that doesn't change that (simplified) Kelvin is just a version of Celsius that has a lower starting point (To show you, these are some values of Kelvin(K) and Celsius(C) next to each other: K=0 = C=-273, K=273 = C=0, K=373 = C=100). This made Kelvin very easy for me to learn as a child, because it was just -273 of anything I knew already. Kelvin isn't as easy for someone who grows up with Fahrenheit. So logically someone who doesn't grow up with celsius probably makes more mistakes using Kelvin. Which means that you could argue that growing up with Fahrenheit is disadvantageous for these people if they want to enter the scientific field.
Since this is the only thing that truely differenciates Celsius from Fahrenheit aside from personal preference, I hereby declare that Celcius is better than Fahrenheit!
For me this is just a fun brain exercise. Please prove me wrong if you can, hope this was good food for thought!
None of this proves why Celsius is better. Because it isn’t better in any way
Long live freedom units! Thanks Kyle!
The term "Freedom units" is actually ironic. We use the system we got from the very nation we went to war against to gain our freedom, WORSE the Metric system was invented by France, The nation that HELPED us gain said freedom. So in REALITY, Metric IS the "freedom units". Also Fahrenheit is neither English or French, We got Fahrenheit from the GERMANS.
Medicine uses Celsius. I got used to it at work.
I tell my Canadian relatives this exact idea all the time. They are reluctant converts to the metric system as is, still preferring to use imperial measurements for things like height, weight and short distances. But they have completely bought in on the centigrade scale for temps. They spend half the year living in below zero temperatures because of this now.
A few F-to-C correspondences are easy to remember:
32 F = 0 C (water freezes, snow becomes possible)
68 F = 20 C (typical indoor thermostat setting in the US)
and from those you can derive one more landmark temperature:
50 F = 10 C (sweater weather)
As a Canadian, I feel that feet, inches, pounds are generally superior to the metric system. Most Canadians use these for heights and weights. Most don't even know their heights in cm or weights in kg because the metric system stinks there.
Canadian here. Nonsense. You're saying Imperial is superior because of ... tradition? (And I do know my height and weight in metric).
@@stephenwodz7593 lol. Have fun giving your weight in kg and having people even know what you're talking about.
I am 1.77 and I have to round up when I convert to limp system. Inches don’t have enough resolution.
Sorry Kyle but using the 'common man' usage is a pretty flimsy argument for me!
If you've grown up in Europe the you just know if it's 35C then it's going to be a sweltering day and likewise if they say it's going to be 5C then you know to crank up the heating and put a sweater on under your cost when you go out.
The reason given in effect is only that Fahrenheit is better for US citizens because they're familiar with it. In short: continue using what you're accustomed to (which is fine of course).
Neither valid pros nor cons given.
I think what Kyle is saying is that it’s designed for common man. I know people are used to it but people can get used to almost anything. 0-100 makes more sense from a design perspective. 0 - 40 does not.
@@jeffwatson7315 Not only a 0 to 100 scale more intuitive than a 0 to 40 scale, the 0 to 40 scale also doesn't cover the habitable environment as well; at 0 degree Celsius you don't even see snow.
It is easy to convert Celsius to kelvin, just add absolute temperature that is 273.15. Celsius is highly logical, Zero means freezing, 18 to 25 is pleasant, 30+ is hot 35+ very hot, 40+is heat wave. For. Those living in a tropical region, Celsius is the best. Fahrenheit has many range, that human doesnot need. We just need, is it freezing , boiling, at what pressure (cooking). Sorry, I will take Celsius
I agree completely! As an American, I wish were used the metric system. However, Fahrenheit is better for the reasons stated and should be kept. the thing about temperatures compared to the other forms of measurement is that temperature is linear, we never have to convert temperatures within a scale unlike figuring out how many inches are in a mile or centimeters in a kilometer (of course that one is easy). A temperature just is and you only need to convert when jumping from one system to the other. Great explanation about these systems.
Another thing about the freezing and boiling points; Those only work if you're at sea level. If you're up at altitude water boils at a lower temperature because there's less atmospheric pressure which also impacts when water boils. Anyone who lives in mountain areas already knows that cooking times are slightly longer because of this.
Agreed about no conversion within one system.
However, usually you buy the themometer labelled with he scale -- If you have to do it, only needing pure water under certain conditions would still be easier to reproduce than saltwater under certsin conditions plus "the average body without fever".
Kyle, I gotta admit I was skeptical of the title...totally NOT click bait! You're right, and I never even knew how convenient fahrenheit is, as an American!! Big props and thanks for another great video!!!
Total BS. The only reason he states the F is better is because he grew up with it and used to it. The only difference between two I’d the starting point. How often in life you will use absolute zero degrees?
It's the exact opposite. You only think Celsius is better because you are familiar with it. Also, absolute zero is necessary for scientific calculations.
He’s finally lured us into his dark ideological terrain
You’re completely right, as a scientist Kelvin is clearly the better system for chemical and physical calculations and 0-100 F is a physically relevant range for human experience. 0 C is irrelevant because it doesn't even guarantee you see frozen precipitation, usually it has to be colder than that for the snow to stick around at all, and 100 C is a bad time if you are personally experiencing it.
I've been saying this for years! Farenheit for weather, Celsius for cooking!
Also I agree the metric system is largely superior, but it's biggest weakness in my opinion is that it lacks a unit measurement for the length of about 1 foot. It's such a convenient unit length to have as there are so many things that aren't nearly a meter but are way longer than a centimeter
Millimeter, centimeter, decimeter, meter, dekameter, hectometer, kilometer. It is called decimal system for a reason.
@@chefnycThey is right though that some are used more than others ;-)
How frequently you need it depends what you are doing. On which depends the required precision.
Possibly:
1 ft ~ 30 cm ~ 1/3 m
2 ft ~ 60 cm > 1/2 m (roughly of course, else you wouldn't miss feet anyways)
If you're not accustomed to foot, you don't actually miss it, my personal experience.
In order to convert from C. to F., all you have to do is know 4 numbers and interpolate:
-40 C = -40 F
0 C = 32 F
23 C = 73 F
40 C = 104 F
Most everything in the external temperature range, which constitutes most people's experience, lies between those numbers. Even for temps above 104 F you can extrapolate.
Agreed...but I'll go further...my car gets 12,000 furlongs to the hogshead and I'm damn proud of it!
Fahrenheit is only better because you grew up with it and are used to it.
There are several people in the comments that state why it is better. Most notably, it is a finer scale.
I'd say it's the exact opposite.
@@GeographyKing Ehhh, my coworkers who grew up abroad have a great intuitive understanding of celsius and no clue about Fahrenheit. It's intuitive to me and not at all to them.
When Fahrenheit found his scale he based it on the temperature at which seawater froze. That became zero degrees. He set a mark for the freezing of fresh water, which he found at 32.
To set the temperature of the 'opposite' of freezing: boiling. On a circle, opposites are 180 degrees apart. 32 degrees (freezing) and 212 degrees (boiling) put his scale in that 'human experience' zone which you describe. As another comments here, it is the scale that humans feel/experience.
100% correct. plus the boiling point of water totally depends on pressure (water boils at 95º C in Denver CO)
Yes, and water boils at different Fahrenheit values too. Duh. The American system is trash, which is why almost nobody in the world uses it.
In C I like that 0 is freezing, 10 is as cold as I ever want it, 20 is room temperature, 30 is hot, and 40 is hot AF. See? Easy!
What about the three months of the year that are below freezing?
@michaelwald6671 Any negative number = "why are you outside? Go inside!"
@michaelwald6671 “Below freezing”? You mean “below 32”? Americans should use “below 32” when talking about icy conditions
As an American, if I see Celsius on on a thermostat, I quickly press the button to change it back to Fahrenheit.
The way I see it, the crux of the argument is largely, "Fahrenheit is what I'm familiar with, so it makes more sense to me" -- the same thing my high school students would say about Celsius.
When you're in a place that often sees temperatures just above or just below freezing, Celsius is a HUGE advantage: -1, the road could be icy, +1 and you're probably fine. You don't have to be that familiar with the scale to know what it represents, you know that negative numbers mean slippery surfaces.
But to the first point... if you grew up with Celsius -- which I didn't, as I grew up near Detroit on the Canadian side and we always watched American newscasts in Fahrenheit -- that's going to just seem more natural to you. A hot summer day is 30 and above; a cold winter night is -20 (or, if you're in Saskatoon, -40). So on those grounds it's a matter of taste -- but as someone who's fully converted to Celsius for everyday use, I can assure you that I'm at no disadvantage because, say, Fahrenheit is a finer-grained system (it's irrelevant most of the time).
If you're trying to make an argument on "human experience" grounds... some people find 40 F unbearably cold, and some (like me) find 90 F unbearably hot. Humans have a wide range of experiences and sentiments, but basing a temperature scale on the cold sterility and unwavering (mostly) properties of water, that's just good sense.
In conclusion, the imperial system is just stupid and it all needs to go. Those NASA scientists that forgot to convert one thing from imperial to metric and lost a multi-hundred-million-dollar Mars mission... none of that would've happened if the US had the guts to fully commit to metric in the '70s like they promised they would. Plus, basing the length of something on the king's actual foot? Madness.
And finally... because the US is so close to us, and so dominant, they are effectively preventing Canada from becoming as metric as we should be. I know my height in feet and inches better than in centimetres, and that's just not right.
I live in Minnesota which frequently gets below freezing and usually stays below freezing most of the winter.
Its not hard to remember 32 F. It really isnt.
Wrong
Roads don't usually get icy at 32°, because most places with real winters will dump salt and brine on the roads.
Salt becomes ineffective at--you guessed it--Zero degrees Fahrenheit.
@michaelwald6671 Also roads arent gonna freeze right away lol Its not like it drops from 33 to 32 and all of a sudden, a puddle of water is a sheet of ice.
It also wont make a perfectly dry surface become icy.
100% agree
I've argued this for years. We don't base our lives on the boiling point of water at sea level. However, measuring distance, the metric is far superior.
The only time my life is really dependent on a Thermometer is if I need to know the severity of a fever.
For weather they could use words instead of temperature. For my barh or tea I just feel it
So, precise measurement is needed for orher things, like the washing machine, car coolant...
FLIGHT b741 SPOTTED!!!!! GIZZHEAD CONFIRMED

Hello Evel Knievel!
Sigh. This old saw.
"50 being right in the middle is not going to be either hot nor cold, it's going to be pretty mild." This is not true for anyone brought up in a temperate climate. 70°F is comfortable for a normal person. 50°F would be at least sweater weather for the average person. 75°F would be still be comfortable, not warm, to most people. 100°F would be heat warnings in most places. 0°F would be "you will die without proper equipment" in most places. 32°F is the freezing point of water and very, not kinda, cold.
If you want a glimpse into madness, go lookup the actual reasons for the specific 0°F and, well, other measurements of the Fahrenheit scale (there is no specific reason for its 100°F as far as I could find). It's completely arbitrary lunacy that doesn't seem to even have a consistent explanation, other than being consistently bizarre.
I live in the US and use Fahrenheit regularly but I don't go around trying to justify it.
The justifying comes from the Celsius defenders. Commonality does not equal superiority.
@@GeographyKing You literally just made a video justifying the Fahrenheit scale. I'm not making this a "my system's better than your system" debate. I didn't defend any particular scale in my comment. Use whatever system you want. But, the Fahrenheit scale is absolutely not a scale for humans. Like I said, I mostly use the Fahrenheit scale but I don't defend it because it's not any better than any other scale and there are clear drawbacks.
And, seriously, read the wiki page on how the Fahrenheit scale was calibrated. I defy you to claim it's a rational system after reading its history. Its multiple choice history.
I came here thinking oh cmon don't be so proud and I left convinced you're right. I never considered the 0-100 range and it makes complete sense.
As an engineering student, if I'm given a problem where temperature is a factor, Celsius is a lot easier to work with and what I'll always prefer. If I need to know what to wear, I'm using Fahrenheit because it makes intuitive sense, the 0 to 100 portion tells me how comfortable it is, anything above or below that tells me how much faster I'm gonna die outside.
Celcius advocates tout the superiority of the metric system without understanding why the metric system is superior.
I'm a math nerd so I know all the conversions by heart since I was like 8 or something.
Agreed! I have been saying this for years. Americans should probably switch to metric for everything else, but the rest of the world should really get on the Fahrenheit train.
America is metric officially, but the federal government has no authority to force people to use it outside if the FDA. Which is why all food and drugs must be labeled in MKS
There is no "Fahrenheit train". The rest of the world will continue using Celsius, and America will eventually join them.
@@chachar7458also don’t forget other countries used to use Fahrenheit too back in the old days, but they switched
The pneumonic I learned for Celsius is: 30 is hot, 20 is nice, 10 is cool and 0 is ice. For me this is just a way to understand temperature maps in Europe, Asia, etc... so when you travel you can kinda understand the weather forecast and understand why upper 30s and 40s in the UK last year was so unbearable.
as a climate science graduate, nobody, and i mean NOBODY ever uses farenheit, and nobody ever will.
All the Europeans accusing you of being American-- when Fahrenheit was invented in Europe.
Also Europe used to use Fahrenheit too before they switched
Andres Celsius was 43 when he passed but Dan Fahrenheit insisted he was really was 109.
Growing up in Canada I always liked the symmetry of Celsius: about half the year is above 0 and half is below. The distance from 0 tells you how warm or cold it is.
The 0-100 idea with Fahrenheit is nice, except for the fact that certain areas routinely see temperatures outside this range.
Ultimately I think it’s a toss up.
In most countries it isn't below 0C for half of the year.
My thoughts exactly. As a Canadian I grew up with F. and stick with it even after the country went metric. Prefer metric in everything except temp. for all the reasons outlined by G.K.
Remember:
0C = 32F
10C = 50F
20C = 68F
30C = 86F
40C = 104F
-40C = -40F
Honestly the worst measurement is time and everyone uses it.
including number of days in a month. What a rubbish! Try moving out of your apartment on the 5th of a month. Landlord will prorate your rent differently in February vs March.
And how would you change time? The number of days, the number of months, or the span of a year??? Just curious...
@@chefnycThat's why I don't rent, I own. I pay my monthly mortgage 12 times a year, don't care about the number of days each month. And my equity grows every year, so if I move, I just sell for a large profit. If I don't sell, nothing changes except for yearly increases in homeowners insurance & sometimes property taxes, always more than offset by continued growing equity. Win-win... oh, and a mortgage is cheaper than rent even during inflation. Paying rent is insane, a money pit, a losing proposition. Always own, never rent.
O° C = freezing
5° C = cold 10° C = cool 15° C = mild 20° C = room temperature 25° C = warm 30° C = hot
Conversion algorithm: multiply Celsius temperature by 9/5 and then add 32. Gives you a rough approximation.
Even my Canadian friends begrudgingly admit that 100F conveys a more accurate feeling than 38C (or whatever the conversion is). And who really thinks 19C is a nice day? Nerds. That's who. 75F is way more obviously a nice day.
What's wrong with nerds?
Been saying precisely this for years
Fahrenheit is perfect for weather because you know 100 is too damn hot, 0 is too damn cold, and 69 is nice.
American, here. Celsius is better than Fahrenheit when it comes to doing math and science. Its obviously not as good as kelvin, but it’s on the same scale as kelvin. In order to convert from Celsius to kelvin, all you have to do is add 3 hundred something, I forgot the exact number. So all the math is the same, just have to add that bit in the beginning.
Also, as someone else mentioned, Celsius is useful for dealing with water. We deal with water when we cook. 0 and 100 are easy to remember, 0 for freezing/melting and 100 for boiling/condensing.
