League (unit)

A league is an old unit of length. It was the distance a person could walk in about one hour. The Romans adopted the league and it became a common unit of measurement throughout western Europe and Latin America.

In English-speaking countries the league was usually three statute miles (4.828032 kilometres) on land or three nautical miles (5.556 km) at sea. However, in writing the word league often means the Spanish, Portuguese or French league.^[1]
