Micrometers to Millimeters: the quick answer
1 µm = 0.001 mm
1 micrometer equals 0.001 millimeters
To convert micrometers to millimeters, multiply the value by 0.001. To go the other way, multiply millimeters by 1,000 to get micrometers.
To convert micrometers to millimeters, multiply the value by 0.001. To go the other way, multiply millimeters by 1,000 to get micrometers.

Micrometer (µm). A micrometer (micron) is one millionth of a meter, used for cells, bacteria and fiber thickness.
Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
There are 0.001 millimeters in one micrometer.
Multiply the number of micrometers by 0.001. For example, 10 micrometers equal 0.01 millimeters.
One millimeter equals 1,000 micrometers.
1 millimeter. Other common values: 100 micrometers = 0.1 millimeters and 10,000 micrometers = 10 millimeters.
