For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Typically the even number gauges are used more frequently.
Corresponds to the standard steel thickness of 0 0329 inches 0 84mm.
The gauge number 18 holds no relevance to the actual measurements.
Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.
