About this conversion
The um (um) is a unit of length in the its own measurement system, commonly used for various fields. The millimeter (mm) belongs to the metric (SI) and is typically found in measurements related to engineering and manufacturing tolerances and bolt and screw dimensions. One millimeter is one thousandth of a meter (0.001 m). The conversion factor between these two units is 0.001: multiplying any value in um by this number gives the equivalent in mm. For example, 10 um equals 0.0100 mm. Going the other direction, 1 mm equals 1000 um.
