The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
Sheet metal gauge to mm.
Sheet metal manufacturing and services 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.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
The gauge number 18 holds no relevance to the actual measurements.
For a more comprehensive gauge chart you can check out our sheet metal gauge chart here.
As the gauge number increases the material thickness decreases.
This is known as the manufacturers standard.
The larger the gauge number the thinner the metal.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.
In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.
The story of gauge.
In most of the world sheet metal thickness is consistently specified in millimeters.
The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.
A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.
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.
Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
Gague are used to specify the thickness of a metal sheet.
Corresponds to the standard steel thickness of 0 0329 inches 0 84mm.
