Convert megaparsec to astronomical unit
Please provide values below to convert megaparsec [Mpc] to astronomical unit [AU, UA], or Convert astronomical unit to megaparsec.
1 Mpc = 206264806233 AU, UA. To convert megaparsec to astronomical unit, multiply the value by 206264806233; to go the other way, divide by it (1 AU, UA = 4.8481e-12 Mpc). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Mpc = 206264806233 AU, UA
- 1 AU, UA = 4.8481e-12 Mpc
- 10 Mpc = 2.0626e+12 AU, UA
- 100 Mpc = 2.0626e+13 AU, UA
How to Convert Megaparsec to Astronomical Unit
1 Mpc = 206264806232.967 AU, UA
Example: convert 15 Mpc to AU, UA:
15 Mpc = 15 × 206264806232.967 AU, UA = 3093972093494.51 AU, UA

Megaparsec
A megaparsec is a unit of distance used in astronomy, equal to one million parsecs.
History/Origin
The parsec was first coined by British astronomer Herbert Hall Turner in 1913. The megaparsec came into use as astronomical distance measurements extended to other galaxies.
Current Use
The megaparsec is used to measure the distances between neighboring galaxies and galaxy clusters.
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.
