Mils vs. Microns

by Esther Mar | Aug 22, 2018


Mil -
A unit of measurement in the English system that is measured in thousandths of an inch.

(i.e., .001″ = one thousandth of an inch or 1.0 mil)


Micron - A unit of measurement in the metric system that is equal to one thousandth of a millimeter.

(also called a micrometer, abbreviated ‘μm’)


For the conversion:

Mils to Microns: (Number of Mils) x 25.4 (i.e., 0.75 mil = 19 microns)

Microns to Mils: (Number of Microns) / 25.4 (i.e., 14 microns = .55 mil)
