Convert millimeter to astronomical unit
Please provide values below to convert millimeter [mm] to astronomical unit [AU, UA], or Convert astronomical unit to millimeter.
1 mm = 6.6846e-15 AU, UA. To convert millimeter to astronomical unit, multiply the value by 6.6846e-15; to go the other way, divide by it (1 AU, UA = 1.4960e+14 mm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mm = 6.6846e-15 AU, UA
- 1 AU, UA = 1.4960e+14 mm
- 10 mm = 6.6846e-14 AU, UA
- 100 mm = 6.6846e-13 AU, UA
How to Convert Millimeter to Astronomical Unit
1 mm = 6.68458712226845e-15 AU, UA
Example: convert 15 mm to AU, UA:
15 mm = 15 × 6.68458712226845e-15 AU, UA = 1.00268806834027e-13 AU, UA

Millimeter
A millimeter is a unit of length in the metric system, equal to one-thousandth of a meter.
History/Origin
The prefix "milli-" comes from the Latin word "mille," meaning thousand. The millimeter was part of the original metric system adopted in France in 1795.
Current Use
The millimeter is widely used in engineering and manufacturing for high-precision measurements. It is also a common unit in construction and for measuring small objects.
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.
