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