The following charts give typical astm and ansi steel sheet mechanical tolerance ranges. Sheet metal guage tolerances. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
