Mil (mil). A mil, also called a thou, is one thousandth of an inch (0.0254 mm), used for thin films, wire and coatings.
Micrometer (µm). A micrometer (micron) is one millionth of a meter, used for cells, bacteria and fiber thickness.
There are 25.4 micrometers in one mil.
Multiply the number of mils by 25.4. For example, 10 mils equal 254 micrometers.
One micrometer equals 0.0393701 mils.
304.8 micrometers. Other common values: 5 mils = 127 micrometers and 100 mils = 2,540 micrometers.
