Convert astronomical unit to Earth's equatorial radius
Please provide values below to convert astronomical unit [AU, UA] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to astronomical unit.
1 AU, UA = 23454.791062 R_e. To convert astronomical unit to Earth's equatorial radius, multiply the value by 23454.791062; to go the other way, divide by it (1 R_e = 4.26352124543e-05 AU, UA). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
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.
