Pole
A pole is a unit of length equal to a rod or perch, which is 16.5 feet.
History/Origin
The term "pole" as a unit of length originated from the use of a physical pole of a certain length for measuring land.
Current Use
The pole is an archaic unit of measurement.
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.
