How many fathoms to a league?

There are 120 fathoms in a league. A league is traditionally defined as three nautical miles, and since one nautical mile is equal to 60 fathoms, multiplying 60 by 3 gives you 180 fathoms in a league. However, in historical contexts, a league can also be defined as 3 miles on land, which would equal 150 fathoms. Thus, the specific conversion can depend on the definition used.
