Nautical Miles (nmi)
Definition
A nautical mile (nmi) is a unit of length equal to exactly 1,852 meters (approximately 1.15078 statute miles). It corresponds to one minute of latitude along any meridian.
History
The nautical mile originated from maritime navigation, where it was practical to link distance to the Earth's geometry. It was internationally standardized to 1,852 meters in 1929 at the First International Extraordinary Hydrographic Conference.
Current use
Nautical miles are the standard distance unit in maritime and aviation navigation worldwide. Air traffic control, shipping routes, and territorial water boundaries are all measured in nautical miles.
Kilometers (km)
Definition
A kilometer (km) is a metric unit of length equal to 1,000 meters. It is the standard unit for expressing long distances in the metric system.
History
The kilometer was adopted as part of the metric system in 1795. It became the standard long-distance unit across most of the world, though the United States, United Kingdom, and a few other countries still primarily use miles.
Current use
Kilometers are used worldwide for road distances, geographic measurements, running and cycling events, vehicle odometers (in metric countries), and aviation altitude in some regions.
