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.
Twip
A twip (twentieth of a point) is a unit of typographical measurement equal to 1/1440 of an inch.
History/Origin
The twip was invented by Microsoft as a device-independent unit for layout calculations in its software.
Current Use
The twip is used internally by some software programs for screen and print layout.
