Mile
A mile is a unit of length in the imperial and US customary systems of measurement. The international mile is defined as exactly 1,609.344 meters.
History/Origin
The word "mile" comes from the Latin "mille passus," meaning "a thousand paces." The Roman mile spread throughout their empire. The English statute mile was established by an Act of Parliament in 1592.
Current Use
The mile is used for measuring distances on roads in the United States and the United Kingdom. It is also used in horse racing.
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.
