Convert astronomical unit to micrometer
Please provide values below to convert astronomical unit [AU, UA] to micrometer [µm], or Convert micrometer to astronomical unit.
1 AU, UA = 1.4960e+17 µm. To convert astronomical unit to micrometer, multiply the value by 1.4960e+17; to go the other way, divide by it (1 µm = 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 µm
- 1 µm = 6.6846e-18 AU, UA
- 10 AU, UA = 1.4960e+18 µm
- 100 AU, UA = 1.4960e+19 µm
How to Convert Astronomical Unit to Micrometer
1 AU, UA = 1.495978707e+17 µm
Example: convert 15 AU, UA to µm:
15 AU, UA = 15 × 1.495978707e+17 µm = 2.2439680605e+18 µm

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.
Micrometer
A micrometer, also known as a micron, 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 "micrometer" became the official term.
Current Use
The micrometer is a common unit for measuring the wavelength of infrared radiation, as well as the size of biological cells and bacteria. It is also widely used in technology and engineering.
