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.
Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
