Good to Know About Nautical Miles to Leagues Conversion
The league was the NM's predecessor for sea distances. Both come from the same need: measuring how far a ship has sailed. The NM won because it connects directly to latitude (1 arcminute = 1 NM). The league lost because it meant different things in different countries. Precision beat tradition.

Non-Frequently Asked Questions About Nautical Miles to Leagues
Questions nobody should ask - but someone did.
-
Verne wrote in leagues (the French lieue, about 4 km). Modern submarines navigate in NM. Nemo would need to update his charts. '20,000 Leagues Under the Sea' in modern units would be '52,140 Nautical Miles Under the Sea.' Less poetic but more navigable.
-
A nuclear submarine patrol might cover 20,000-30,000 NM submerged. That is about 7,670-11,505 leagues. So modern submarines regularly complete about half of Nemo's famous voyage. Reality caught up with fiction.
-
Because the league varied by country (French, Spanish, Portuguese, English leagues were all different). The NM is universal: 1 arcminute of latitude everywhere. Standardization killed the league. When your unit means 5 different things to 5 different navies, confusion becomes dangerous.
