Convert megameter to astronomical unit
Please provide values below to convert megameter [Mm] to astronomical unit [AU, UA], or Convert astronomical unit to megameter.
1 Mm = 6.68458712227e-06 AU, UA. To convert megameter to astronomical unit, multiply the value by 6.68458712227e-06; to go the other way, divide by it (1 AU, UA = 149597.8707 Mm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference

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.
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.
