Both, nautical mile and metre are derived from earth’s dimensions: One nautical mile is an arc secondminute at the equator, i.e. its circumference is 360·60 NM = 21,600 NM. One metre originally was 1/40,000,000 of the circumference through the poles (or 1/10,000,000 of the distance from a pole to the equator).
Edit: Forgot three zeros in the definition of a metre.
It’s 5280. It’s not hard to remember if you have an IQ above absolute freezing.
YSK only three countries on Earth use the Imperial system of measurement, Myanmar, Liberia, and the U.S. The hostility is not needed.
It’s very easy if you remember that are 3 feet in a yard, 22 yards in a chain, 10 chains in a furlong, and 8 furlongs on in a mile!
but what if they’re above water and we need to use nautical miles?
Those are actually much saner: 10 cables in a nautical mile and 100 fathoms in a cable.

Ah, now it makes sense!
What’s absolute freezing? Did you mash up absolute zero, as in zero degrees Kelvin, with freezing, as in zero degrees Celsius?
Yes actually.
