About these units
Foot (US Survey) (ft (US))
The US Survey Foot is a standardized version of the foot, defined as exactly 1200/3937 meters (~0.30480061 m). It was adopted to maintain continuity with older surveying records when converting to the metric system. Surveyors, engineers, and geographers in the United States used this unit for mapping, cadastral surveys, and infrastructure projects. Its slight difference from the international foot allows historical survey data to align accurately with modern geodetic coordinates. Although the international foot is now more common, the US survey foot remains relevant for interpreting historical survey data and legal property boundaries.
Nautical League (Int) (nl (int))
The international nautical league is defined as 3 international nautical miles, or 5,556 meters. It simplifies the expression of moderately large maritime distances by grouping nautical miles into a more manageable larger unit. Because nautical miles relate directly to Earth's geometry, the nautical league also maintains a connection to latitude and longitude. While not widely used in modern navigation—pilots and mariners typically stick to nautical miles and knots—nautical leagues still appear in older literature, historical accounts of sea voyages, and some naval traditions. They offer narrative convenience when describing long journeys without resorting to extremely large numbers. The unit highlights the tendency of sailors to create practical, scaled units that simplify communication during long-distance travel.
