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.
Link (Us Survey)
A U.S. survey link is a unit of length equal to 1/100 of a U.S. survey chain.
History/Origin
The U.S. survey link is based on the U.S. survey foot. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey link was used for land surveying in the United States.
