Sheet Metal Gauge To Mm Conversion Formula

Converting sheet metal gauge numbers to millimeters is as simple as following the chart below.

Sheet metal gauge to mm conversion formula.

Wire cross sectional area calculation. Gauge to mm inches converter. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Sheet metal gauge thickness chart.

Typically the even number gauges are used more frequently. Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Click here for a gauge to mm conversion chart.

The unit to measure the thickness of the steel or sheet metal is called as the gauge. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different. The old metallurgical engineer says. Believe it or not the definition of gauge in mm is different for carbon steel stainless steel galvanized steel aluminum brass and copper.

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. There is no conversion formula due to the difference between ga. The comparison of different unit systems is shown in the table below. This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.

You can find the gauge to mm inch conversion for sheet metal by the chart below. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. A n mm 2 π 4 d n 2. In this conversion calculator you can convert gauge to inches and millimeters from the known gauge number.

The n gauge wire s cross sercional area a n in square millimeters mm 2 is equal to pi divided by 4 times the square wire diameter d in millimeters mm. Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively. Swg to mm conversion chart. Most used steel sheet metals have gauge values between 30 and 7.

How gauge to mm is different for different material. This website provides detailed information on the gauges expressed.
