A land mile was historically established as a specific number of smaller length measures (feet, yards etc.), and has been in existence since Ancient Rome.
A nautical mile was established as a 1/60th fraction of one degree of latitude, since its useful to be this way in navigation, and also because that’s how you measure distances at sea (and not by counting feet or yards).
