Most used steel sheet metals have gauge values between 30 and 7. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different. Sheet metal gauges work opposite to what one might consider the norm.
Corresponds to the standard steel thickness of 0 0329 inches 0 84mm. Is different from inches there is no conversion formula. These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm.

Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts.
Working with sheet metal as shown in figure 1 gauge sizes can be confusing at the best of times. You can find the gauge to mm inch conversion for sheet metal by the chart below. Sheet metal gauge to mm. Converting sheet metal gauge to thickness in inches.
In this conversion calculator you can convert gauge to inches and millimeters from the known gauge number. Hence 4 gauge material is thicker than 6 gauge material. The gauge number 18 holds no relevance to the actual measurements. The thickness of sheet metals is specified by gauge.
