How To Measure Sheet Metal Gauge

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

How to measure sheet metal gauge.

Essentially one inch is equal to 25 4 millimeters or 0 0254 meters. Metal sheet thickness is measured in gauge. 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. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

When working with sheet metal the term gauge is often used. Gague are used to specify the thickness of a metal sheet. Since ferrous and non ferrous metals of the same gauge have different thicknesses different metal gauge tools are used to measure ferrous. On the smaller side 7 gauge sheet metal equals approximately 0 1875 inches.

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. Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. The table below provides conversion to inches. If your measurement was 55.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. The most commonly used sheet metal sizes range from 30 gauge thinner to 7 gauge thicker. How to measure sheet metal gauge thickness. Use the millimeter hash marks to find the most accurate measurement.

It might be obvious to some but also less obvious to others more and more these days fabricators take delivery of their sheet metal do what needs to be done then simply ship it onwards knowing already that its dimensions and thickness are correct all is well and never even needing a sheet. Use a tape measure to find the thickness of your sheet metal piece. The gauge number 18 holds no relevance to the actual measurements. Different gauge thickness applies to different metals.

A gauge is a traditional non linear measurement. Multiply the number of millimeters by 0 03937 to convert to inches. A sheet metal gauge tool is used to measure metal thickness and show both the gauge number as well as the thickness of the metal in thousandths of an inch.
