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.
Hand
A hand is a unit of length equal to 4 inches.
History/Origin
The hand was originally the width of a man's hand, including the thumb. It was standardized to 4 inches for measuring the height of horses.
Current Use
