Convert astronomical unit to micron
Please provide values below to convert astronomical unit [AU, UA] to micron [µ], or Convert micron to astronomical unit.
1 AU, UA = 1.4960e+17 µ. To convert astronomical unit to micron, multiply the value by 1.4960e+17; to go the other way, divide by it (1 µ = 6.6846e-18 AU, UA). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 AU, UA = 1.4960e+17 µ
- 1 µ = 6.6846e-18 AU, UA
- 10 AU, UA = 1.4960e+18 µ
- 100 AU, UA = 1.4960e+19 µ
How to Convert Astronomical Unit to Micron
1 AU, UA = 1.495978707e+17 µ
Example: convert 15 AU, UA to µ:
15 AU, UA = 15 × 1.495978707e+17 µ = 2.2439680605e+18 µ

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.
Micron
A micron is a non-SI name for micrometer (µm), which is a unit of length equal to one-millionth of a meter.
History/Origin
The term "micron" and the symbol µ were officially declared obsolete by the General Conference on Weights and Measures (CGPM) in 1967 and are now discouraged.
Current Use
While the term micrometer is the officially recognized term, "micron" is still used in some industries and in casual speech.
