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 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.
