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.
Megameter
A megameter is a unit of length in the metric system equal to 10^6 meters.
History/Origin
The prefix "mega-" for 10^6 was adopted by the CGPM (General Conference on Weights and Measures) in 1873.
Current Use
The megameter is sometimes used to specify the diameters of planets and the distances of satellites.
