Conversion from (Gauge to Inch/MM) Sheet Steel Thickness Data Table  

Data table of Sheet Steel Gauge Thickness specifications, the thickness data comes from many references and is accumulated here.

The Table below is as good a reference as to converting from Gauge to Inch to mm.

It lists two of the following standards

BWG - Birmingham Wire Gauge for Iron & Steel Wire
USG - US Standard Gauge for Stainless Steel

Different materials such as stainless steel & aluminium may vary slightly on their dimensions, but the data should be accurate for most everyday purposes with a slight tolerance but to the temperature of the day.
