There are several different gauge systems used today with specific gauge designations used for specific metal types.
Wire gauge is a measure for the size of a wire either in diameter or in cross sectional area.
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.
Converting sheet metal gauge numbers to millimeters is as simple as following the chart below.
For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.
