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 (Uk)
The UK nautical mile, or Admiralty mile, was defined as 6,080 feet.
History/Origin
The British Admiralty defined its nautical mile as a thousandth of an imperial nautical mile. The UK adopted the international nautical mile of 1,852 meters in 1970.
Current Use
