I knew it was almost the same as a mile but I forgot. But I never knew where it came from. This helps. actually quite elegant reason for the nautical mile.
That's a great video thanks. I came to watch this after researching how 1 metre is defined. It originates from - The total metres from the north pole to the equator = 10,000,000 metres. 1 nautical mile is 1 minute, which in km is calculated as 10,000,000 / 90 (for 1 degree) / 60 (for 1 minute) = 1,851.85 metres, the same as in your video!

I'm really having trouble with this. The last guy said 1 Nm is equal to 1 minute of degree based on the circumference of the earth at the equator. Your saying it's based on 1 minute along a line of longitude. But your distances would not be uniform due to the Earth being an oblate sphere. In other words, a Nm closer to the poles would be longer than a Nm in the tropics. This is because, due to the oblate shape, the radius of a certain arc increases as we approach the poles and decreases as we approach the equator. Hence the distance of one minute is longer relative to the longer radius of that certain arc that is closer to the poles. OK, that's it, I'm going to bed before I launch my turret like a T72.
Thank you Michael for visiting my channel. Distance here is measured in degrees, 1/60 of a degree is one minute. Angle in degree will not change either earth is uniform or not. For example: 60 degree angle stays same either you measure with respect to a sphere, oval or any other shape. I hope it will help to clarify the doubt.
You're absolutely right! SO many countless options, but quick, easy, succinct, and easy for metric or imperial system users. We should delete all the other convoluted videos lol
Best and Easiest of ALL of the vid options. Illustration in 2D is super easy to understand. Quick, Easy, Succinct, for metric or imperial system users. One question, were you referring to the lines of *longitude* as lines of *latitude* accidentally? Given it's a globe, it's the same angle regardless though correct?
Thanks Ethan, I am glad you liked the video. It is one minute of latitude along any line of longitude. I mark one minute on the line of longitude. Many students i met get very confused with this topic. I hope I was able to explain it with this video. Thank you, Happy Teaching✌️
if my mom was traveling at 6KM along the equator going east and your mom was traveling 19.6 MPH along the border going west and both started in Quito Ecuador, what is the coordinates of their meeting place?? AND what would be the speed of their friend traveling due south from the North Pole if she was to arrive 1.25 hour later at the same meeting point.???? Go for that one mr Brainiack!!!!
1 degree of latitude is the definition of 1Nm, this does not mean you are expected to measure your movements against this definition. The conversion is 1,852m. So measure the distance you traveled in any direction in meters, and divide with 1,852 to get the Nautical Mile equivalent.
Every unit of measurement has a definition, for instance one meter is the length of the path traveled by light in a vacuum in 1,299,792,458 of a second, this doesn't mean that if you want to measure something in meters you start looking for a torch light and a vacuum, it's just a definition, the measuring tape is the result of that definition.

For those who are confused when he says “minutes” he does not mean time, he is referring to the distance in between the minutes on a clock ⏰

I wish I could like this video twice
Thank you very much for you support!!
What if you are traveling East-west around the North Pole? Are you going 0knots or 1,000,000 knots?
Thanks for sharing!!
So nautical mile changes from eqator region to poles
very well done!

Sayeeda Jannat thank you! I am glad you like the video.
Good video. But how about for navigational purposes, can you describe seconds and how they are used?
1 second is just 1/3600 degree
if my mom was traveling at 6KM along the equator going east and your mom was traveling 19.6 MPH along the border going west and both started in Quito Ecuador, what is the coordinates of their meeting place?? AND what would be the speed of their friend traveling due south from the North Pole if she was to arrive 1.25 hour later at the same meeting point.???? Go for that one mr Brainiack!!!!
Respect for including imperial measurements for us old (Western) guys 😂

Why nautical mile length is longer at poles than at equator?
Great job.
Great writing with your mouse!
Thank you for visiting my channel. Please share and subscribe to support educational videos.
way cant we use this on land?
Because mountains and hills will make the measurement to be different in every different landscape
If nautical mile is 1 degree of Latitude, what if I travel multiple Latitudes (west to east per reference)?
1 degree of latitude is the definition of 1Nm, this does not mean you are expected to measure your movements against this definition. The conversion is 1,852m. So measure the distance you traveled in any direction in meters, and divide with 1,852 to get the Nautical Mile equivalent.
Every unit of measurement has a definition, for instance one meter is the length of the path traveled by light in a vacuum in 1,299,792,458 of a second, this doesn't mean that if you want to measure something in meters you start looking for a torch light and a vacuum, it's just a definition, the measuring tape is the result of that definition.
One degree is 60 nautical miles...
@@thomasaquinasozoagu7286 1 minute, not 1 degree.
According to this we only measure north south distance... What about east west distance.... How we calculate one minute?
It is same in all directions!!
@@DRMath is that on the assumption the earth is completely spherical ?
So, that means it's only 5400 Nautical Mile from the equator to the North Pole?
Good observation, thanks for sharing!! To be exact 5365.96 Nautical Miles
Thank you 😊

What is wrong if we specify distance in kilometer or mile as we do on land?
I believe it is due the long distances we travel in sea and air.
@2:12 thanks
1:15 y is 1 deg = 60mins ??
how was the time calculated to be 60mins ??
wont the latitude change as we go up so how will nautical mile remain same?
It stays same as unit of distance for example kilometer stays same as you travel along the road.
Is this only in longitude? not horizontal?
Thanks for visiting my channel. I believe it applies in all directions.
I thought 1 degree have 4 mins.
Yes you are right in terms of rotation and time perspective, the sun takes 4 minutes (virtually) to cross one degree longitude (not latitude)
Why is 1 degree, 60 minutes?
Ths
Arc minute
Longitude, not latitude.
Latitude along longitude line.
