A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
How thick is 10 ga sheet metal.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
This is known as the manufacturers standard gage for sheet steel.
Thus a 10.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
As the gauge number increases the material thickness decreases.

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.
For other materials such as aluminum and brass the thicknesses will be different.
Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
