Convert micrometer to astronomical unit
Please provide values below to convert micrometer [µm] to astronomical unit [AU, UA], or Convert astronomical unit to micrometer.
1 µm = 6.6846e-18 AU, UA. To convert micrometer to astronomical unit, multiply the value by 6.6846e-18; to go the other way, divide by it (1 AU, UA = 1.4960e+17 µm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 µm = 6.6846e-18 AU, UA
- 1 AU, UA = 1.4960e+17 µm
- 10 µm = 6.6846e-17 AU, UA
- 100 µm = 6.6846e-16 AU, UA
How to Convert Micrometer to Astronomical Unit
1 µm = 6.68458712226845e-18 AU, UA
Example: convert 15 µm to AU, UA:
15 µm = 15 × 6.68458712226845e-18 AU, UA = 1.00268806834027e-16 AU, UA

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.
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.
Frequently Asked Questions
What is 1 micrometer in astronomical unit?
1 micrometer (µm) = 6.6846e-18 astronomical unit (AU, UA).
How do you convert micrometer to astronomical unit?
Multiply the micrometer value by 6.6846e-18. For example, 25 µm × 6.6846e-18 = 1.6711e-16 AU, UA.
