Formula to convert sheet metal gauge to mm.

Believe it or not the definition of gauge in mm is different for carbon steel stainless steel galvanized steel aluminum brass and copper. Most used steel sheet metals have gauge values between 30 and 7. Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing. Gauge to thickness chart gauge stainless galvanized sheet steel aluminum fraction inches mm inches mm inches mm inches mm 30 0 0125 0 33 0 0157 0 40 0 0120 0 30 0 0100 0 25.

How gauge to mm is different for different material. Sheet metal gauge thickness chart. You can find the gauge to mm inch conversion for sheet metal by the chart below. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.

Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively. The thickness of sheet metals is specified by gauge. In this conversion calculator you can convert gauge to inches and millimeters from the known gauge number. The unit to measure the thickness of the steel or sheet metal is called as the gauge.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. The old metallurgical engineer says. Click here for a gauge to mm conversion chart. These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes.
