The gauge number 18 holds no relevance to the actual measurements.
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.
Gague are used to specify the thickness of a metal sheet.
When working with sheet metal the term gauge is often used.
Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.
Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
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.
A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.
Corresponds to the standard steel thickness of 0 0329 inches 0 84mm.
