Millimeters to micrometers
1 millimeter in micrometers
1 mm = 1,000 µm
µm = mm × 1,000
To convert millimeters to micrometers, multiply by 1,000. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works
The relationship is µm = mm × 1,000. Both units measure length, so the conversion is a fixed factor that never changes.
Common questions
- How many micrometers are in one millimeter?
- One millimeter equals 1,000 micrometers. µm = mm × 1,000.
- How do you convert millimeters to micrometers?
- Use µm = mm × 1,000. So 10 mm is 10,000 µm.
- How many millimeters are in one micrometer?
- One micrometer equals 0.001 millimeters, which is the reverse of the conversion above.
