How to Convert Micrometers to Astronomical Units
The micrometer and astronomical unit are both units of length. By definition, 1 astronomical unit equals exactly 1.496e17 micrometers. This means to convert micrometers to astronomical units, you divide by 1.496e17.
Formula
Step-by-Step Example
Convert 5 μm to astronomical units:
We need to convert micrometers to astronomical units
Since 1 AU = 1.496e17 μm, divide by 1.496e17
5 ÷ 1.496e17 = 3.3422459893e-17
5 μm = 3.3422459893e-17 AU

About These Units
Micrometer (μm)
A micrometer (μm), also called a micron, is a metric unit equal to one millionth of a meter or 0.001 millimeters. Micrometers are used for measuring bacteria (1-10 μm), human hair diameter (70-100 μm), red blood cells (7 μm), and semiconductor features.
Astronomical Unit (AU)
An astronomical unit (AU) is the average distance from Earth to the Sun: approximately 149.6 million kilometers or 93 million miles. AUs measure distances within our solar system. Mars is 1.52 AU from the Sun, Jupiter is 5.2 AU.
