Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
Micrometer (µm). A micrometer (micron) is one millionth of a meter, used for cells, bacteria and fiber thickness.
There are 1,000 micrometers in one millimeter.
Multiply the number of millimeters by 1,000. For example, 10 millimeters equal 10,000 micrometers.
One micrometer equals 0.001 millimeters.
12,000 micrometers. Other common values: 5 millimeters = 5,000 micrometers and 100 millimeters = 100,000 micrometers.
