Convert Earth's polar radius to nautical mile (international)
Please provide values below to convert Earth's polar radius [R_p] to nautical mile (international) [NM], or Convert nautical mile (international) to Earth's polar radius.
1 R_p = 3432.37165227 NM. To convert Earth's polar radius to nautical mile (international), multiply the value by 3432.37165227; to go the other way, divide by it (1 NM = 0.000291343741678 R_p). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
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.
