How to convert millimeters to microns
1 millimeter is equal to 1,000 microns, and 1 micron is equal to 0.001 millimeters. To convert, multiply by the conversion factor:
microns = millimeters × 1,000
microns = millimeters ÷ 0.001Example: convert 15 mm to µ: 15 × 1,000 = 15,000 µ.

About the millimeter
A millimeter is one thousandth of a meter. It's the standard unit in engineering drawings, manufacturing, rainfall and screen and paper sizes.
Symbol: mm · 1 mm = 0.001 m · Category: Metric (SI)
About the micron
The micron is the older name for the micrometer (one millionth of a meter). It's still common in filtration, semiconductor manufacturing and particle sizes.
