Nautical Mile (UK)
The nautical mile (UK) is a unit of distance used primarily in maritime and aviation navigation in the United Kingdom. Traditionally, it was defined as 6,080 feet (about 1,853 meters), which is slightly longer than the modern international nautical mile of 1,852 meters. This UK definition was used before international standardization in 1929. Today, the international nautical mile is widely adopted, but the UK nautical mile historically played an important role in navigation and mapping.
Nautical Mile (International)
A nautical mile (international) is a unit of measurement used primarily in maritime and aviation contexts. It is defined as 1,852 meters or 1.852 kilometers, which is approximately 1.1508 statute miles. The nautical mile is based on the Earth's geometry, representing one minute of latitude along any meridian. This makes it particularly useful for navigation, as distances on charts and GPS systems often relate directly to degrees of latitude and longitude. The international nautical mile was officially adopted by the United States in 1954 and is now used worldwide for consistency in global navigation. It is closely linked with the knot, a unit of speed equal to one nautical mile per hour. The standardization of the nautical mile has greatly simplified communication and coordination in international travel, trade, and defense across oceans and airspace. Its use continues to be essential in global navigation systems today.
