The unit to measure the thickness of the steel or sheet metal is called as the gauge.
Mm to gauge conversion for sheet metal formula.
For a more comprehensive gauge chart you can check out our sheet metal gauge chart here.
This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.
These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes.
The thickness of sheet metals is specified by gauge.
Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing.
Converting sheet metal gauge numbers to millimeters is as simple as following the chart below.
Believe it or not the definition of gauge in mm is different for carbon steel stainless steel galvanized steel aluminum brass and copper.

The old metallurgical engineer says.
Typically the even number gauges are used more frequently.
Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.
Is different from inches there is no conversion formula.
This website provides detailed information on the gauges expressed.
In this conversion calculator you can convert gauge to inches and millimeters from the known gauge number.
Most used steel sheet metals have gauge values between 30 and 7.
The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size.
