Converting sheet metal gauge numbers to millimeters is as simple as following the chart below.
Gauge sheet metal in mm.
This is known as the manufacturers standard.
When working with sheet metal the term gauge is often used.
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.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.
