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.
Rod (US Survey)
The US survey rod is a unit of length used in U.S. land surveying. It is defined as exactly 16.5 US survey feet, which is slightly longer than the international foot. Since one US survey foot equals approximately 0.3048006096 meters, the US survey rod measures about 5.0292 meters.
The survey rod, also called a pole or perch, is historically significant in the U.S. Public Land Survey System and is used to measure land boundaries and distances.
Key facts:
1 US survey rod = 16.5 US survey feet
1 US survey rod ≈ 5.0292 meters
4 US survey rods = 1 US survey chain
40 US survey rods = 1 US survey furlong
Though the US survey foot and related units are being phased out in favor of international units, the US survey rod still appears in legal land descriptions and older surveying documents.
