Please note that astm states in specification astm a480 10a the use of gage number is discouraged as being an archaic term of limited usefulness not having general agreement on. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. When working with sheet metal the term gauge is often used. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. There is no conversion formula due to the difference between ga.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. The larger the number of gauge is the smaller the diameter is. The larger the gauge number the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.
