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.
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.
