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 did not know their origin, that’s hilarious.
