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.
Mile (Statute)
A statute mile is a unit of length equal to 5,280 feet.
History/Origin
The statute mile was defined by an Act of the English Parliament in 1592 during the reign of Elizabeth I.
Current Use
The statute mile is the standard unit for measuring road distances in the United States and the United Kingdom.
