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.
Barleycorn
A barleycorn is an old English unit of length, equal to one-third of an inch.
History/Origin
The barleycorn was a unit of measurement in medieval England, and was originally based on the length of a grain of barley. It was a fundamental unit from which other units were derived.
Current Use
The barleycorn is an obsolete unit of measurement, but it is still the basis for shoe sizes in English-speaking countries.
