Convert micrometer to astronomical unit
Enter a value below to convert micrometer [µm] to astronomical unit [AU, UA]. Reverse conversion: 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.

Micrometer: Definition and Use
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: Definition and Use
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 to Astronomical Unit: Frequently Asked Questions
What is 1 micrometer in astronomical unit?
