Originally used in the fields of medicine and jewellery the larger the number the smaller the diameter and now it is also used to indicate the thickness.
Gages of sheet metal sizes.
Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
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 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts.
Gague are used to specify the thickness of a metal sheet.
The thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.
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.
