Steel Wire Gauge Chart

Wire gauges in approximate decimals of an inch.

Steel wire gauge chart. 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. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. American wire gauge awg sizes and properties chart table table 1 lists the awg sizes for electrical cables conductors. In addition to wire size the table provides values load current carrying capacity resistance and skin effects.

Note w m wire gauge us steel wire gauge and music wire gauge are different systems. The gauge system has long history in metal fabrication. D n in 0 005 in 92 36 n 39. Drill bits conversion chart convert between drill bit dimensions gauge numbers inches and mm.

Wire gauge or the measurement of a wire s diameter is an extremely important measurement for your determining your project s choice of wire. History of the gauge system. Wire gauge dictates the amount of electric current a wire can safely carry its electrical resistance weight and other key characteristics. The n gauge wire diameter d n in millimeters mm is equal to 0 127mm times 92 raised to the power of 36 minus gauge.

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. Wire gauge is a measure for the size of a wire either in diameter or in cross sectional area.

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. Cm circular mil area the circular mil area cm is a unit denoting the cross sectional size of a wire or a cable. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
