Millimeters to micrometers Conversion
1 millimeters (mm) is equal to 1000 micrometers (μm).
1 mm = 1000 μm
or
1 μm = 0.001 mm
Formula
To convert a length from millimeters (mm) to micrometers (μm), multiply the length in millimeters by 1000
l(μm) = l(mm) × 1000
Examples:
Convert 20 millimeters to micrometers:
l(μm) = 20mm × 1000 = 20000 μm
