The smaller the number the thicker the material.
Converting sheet metal gauge to thickness in inches.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
You can find the gauge to mm inch conversion for sheet metal by the chart below.
The gauge number 18 holds no relevance to the actual measurements.
0 0219 0 56 0 0247 0 63 0 0209 0 53 0 0179 0 46.
Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
