Furlong
A furlong is a unit of length in the imperial and US customary systems, equal to one-eighth of a mile, 220 yards, or 660 feet.
History/Origin
The name "furlong" derives from the Old English words "furh" (furrow) and "lang" (long), originally referring to the length of a furrow in one acre of a ploughed open field.
Current Use
Today, the furlong is primarily used in horse racing to state the length of races.
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.
