International Nautical League
The international nautical league is a standardized version of the nautical league used in maritime navigation. It is defined as exactly 3 international nautical miles, which equals 5,556 meters or about 3.45 miles. This standardization helps avoid confusion caused by variations in historical definitions of the league. While the nautical mile remains the primary unit in modern navigation, the international nautical league provides a consistent way to measure longer distances at sea when needed.
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.
