Millimeters to micrometers
Convert millimeters (mm) to micrometers (µm) with our converter. Micrometers, also commonly known as microns, are calculated instantly from the millimeter value you enter.
1 mm = 1,000 µm
Formula
You can use the precise conversion formula below, if you want to convert millimeters to micrometers (mm to µm) manually.
Conversion formula: µm = mm × 1,000
Scientific basis: This relationship is based on SI prefixes, where 1 millimeter equals exactly 1,000 micrometers.
Equivalent value: 1 mm = 1,000 µm
Example: 20 mm = 20 × 1,000 = 20,000 µm
Explanation: To convert millimeters to micrometers, multiply the number of millimeters by 1,000.
