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.
Fingerbreadth
A fingerbreadth is an ancient unit of length, based on the width of a finger, approximately 3/4 of an inch.
History/Origin
The fingerbreadth was a common unit of measurement in many ancient cultures.
Current Use
The fingerbreadth is an obsolete unit of measurement.
