Today I learn that Americans do not even use the nautical miles. You are not happy to have an imperial ton of non divisible units you also need to have fucking homonyms?
The nautical mile comes from the measure of 1 second of arc (°,mn,s) of longitude over the earth. Hence British nautical and French nautical mile conversion were slightly different as they were not defined at the same latitude.
That explains why the people who designed the meter found it logical for it to represent a portion of Earth’s circumference (1/10 000 000 of the equator-pole distance)
I think the most insane combination of units can be found in aviation. They use feet for altitude but nautical miles for distance, then they use knots (nautical miles per hour) for horizontal velocity, but for vertical velocity they use feet per minute.
Nautical miles. The mile that’s actually useful.

I assume americans in the navy use nautical miles.
Imagine using nautical kilometers, road kilometers, space kilometers, imperial kilometers, protestant kilometers…
Now please tell me there are no nautical feet, yards, inches and furlongs

I did not know their origin, that’s hilarious.

Just last week I found this unit right here and I still haven’t stopped chuckling
