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.
Arpent
An arpent is a unit of length and a unit of area. As a unit of length, it is approximately 192 feet.
History/Origin
The arpent was a pre-metric French unit of measurement. It was used in France and its North American colonies, including parts of the United States.
Current Use
The arpent is an obsolete unit, but it may still be found in old land records in some parts of North America.
