The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
Sheet metal gauge to mm conversion formula.
There is no conversion formula due to the difference between ga.
In this conversion calculator you can convert gauge to inches and millimeters from the known gauge number.
This website provides detailed information on the gauges expressed.
This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.
Believe it or not the definition of gauge in mm is different for carbon steel stainless steel galvanized steel aluminum brass and copper.
Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet.
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.
