Plastic Gauge Thickness Chart

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.

Update 2017: New, better ASTM standard D8136 now available for measuring  the thickness of plastic film.
