Yard
A yard is a unit of length in the imperial and US customary systems of measurement, equal to 3 feet or 36 inches.
History/Origin
The origin of the yard is uncertain, but it is believed to have been derived from the length of a man's belt or girdle. The yard was standardized as part of the English (and later British Imperial) system of units.
Current Use
The yard is commonly used for measuring land, in some sports like American football and golf, and for selling fabric.
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.
