Convert astronomical unit to Earth's equatorial radius
Enter a value below to convert astronomical unit [AU, UA] to Earth's equatorial radius [R_e]. Reverse conversion: 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: Definition and Use
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: Definition and Use
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.
