Convert gigameter to astronomical unit
Please provide values below to convert gigameter [Gm] to astronomical unit [AU, UA], or Convert astronomical unit to gigameter.
1 Gm = 0.00668458712227 AU, UA. To convert gigameter to astronomical unit, multiply the value by 0.00668458712227; to go the other way, divide by it (1 AU, UA = 149.5978707 Gm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Gm = 0.00668458712227 AU, UA

Gigameter
A gigameter is a unit of length in the metric system equal to 10^9 meters.
History/Origin
The prefix "giga-" for 10^9 was adopted by the CGPM (General Conference on Weights and Measures) in 1960.
Current Use
The gigameter is used for measuring interplanetary distances, for example, the distance between Earth and Mars.
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.
