A micron, also called a micrometer, is one thousandth of a millimeter. The tool divides microns by 1000 to get millimeters and multiplies by 1000 for the reverse, using the exact SI metric prefixes.
How to use
- Enter the length in microns.
- Keep microns to millimeters, or press Swap for the reverse.
- Read the result in millimeters.
Examples
- A thousand microns:
1000 um = 1 mm - A human hair:
70 um = 0.07 mm
