Gauge Thickness Conversion Chart and Calculator For Plastic Film
The thickness of plastic film is often expressed in gauge, mils and microns. Here is a chart and a calculator to help you move between the units.
A “mil” is 1/1000th of an inch. This can sometimes mean a millimeter to people outside of the United States, so don’t get confused! Gauge is (100) x (mils), so for example 0.3 mils = 30 gauge. To go from mils to microns, you multiply mils x 25.4.
