a sea or nautical mile is one-sixtieth of a degree of latitude, and varies from 6046 feet on the Equator, to 6092 feet at a latitude of 60°
In post #11 you said it was a fixed length. Historically, it's not fixed, as your quote above demonstrates. It only became a standard distance because we made it so.
