Nautical Mile (International)
The international nautical mile is a unit of length used in marine and air navigation, defined as exactly 1,852 meters.
History/Origin
Historically, a nautical mile was defined as one minute of arc of latitude. The international nautical mile was defined by the First International Extraordinary Hydrographic Conference in Monaco in 1929. The United States adopted it in 1954, and the United Kingdom in 1970.
Current Use
The nautical mile is used for maritime and aviation purposes worldwide.
Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
