How to convert Millimeters to Micrometers
Multiply the millimeters value by 1,000: 1 mm = 1,000 µm. Going the other way, 1 µm = 0.001 mm, so divide by 1,000 or use the Micrometers to Millimeters converter.
About these units
Millimeters (mm)
A millimeter is one thousandth of a meter. It is the usual unit for engineering drawings, paper sizes and anything measured finer than a centimeter.
Micrometers (µm)
A micrometer, or micron, is one millionth of a meter. Cells, fine particles and the thickness of thin films are typically measured in micrometers.
