The chart below can be used to determine the equivalent sheet thickness, in inches or millimeters, for a gauge number from the selected gauge size standard. The weight per unit area of the sheet can also be seen in pounds per square foot and kilograms per square meter.
Ga. is different from inches, there is no conversion formula. Even when the non-ferrous metal plate and the steel plate are the same Ga., the thickness is actually different. You can find the gauge to mm / inch conversion for sheet metal by the chart below.

Find the standard thickness of sheet metal in inches and millimeters for different gauges, materials and processing methods. For 20 gauge steel, the thickness is 0.0359 inches or 0.912 millimeters.
The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a "gauge" (sometimes spelled gage) and indicates the standard thickness of sheet metal and wire.For most materials, as the gauge number increases, the material thickness decreases.

26 lip 2024 · This comprehensive chart illustrates the correlation between gauge numbers and the corresponding thickness of steel sheets in both imperial (inches) and metric (millimeters) units. The gauge system, widely used in metal fabrication, provides a standardized method for specifying sheet metal thickness.
