Nautical League
A nautical league is a unit of distance once used at sea, mainly by sailors and navigators. It equals 3 nautical miles, which is about 5.56 kilometers or 3.45 miles. Nautical leagues were used to measure longer distances during voyages before modern navigation tools became common. While the nautical mile is still widely used today in maritime and aviation navigation, the nautical league is mostly obsolete and rarely used.
