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.
Famn
A famn (also spelled fathom in English) is a traditional Scandinavian unit of length used primarily for measuring the depth of water or length of ropes and cables. It is roughly equivalent to 6 Swedish feet, which translates to about 1.828 meters (approximately 6 feet).
The famn is similar in concept to the English fathom, based on the span of outstretched arms.
While largely obsolete today, the famn was commonly used in maritime contexts in Norway, Sweden, and Denmark and remains part of historical measurements.
