Converting sheet metal gauge numbers to millimeters is as simple as following the chart below.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Convert gauges bwg usg to inches and millimeters.
8 gauge 4 115 mm.
The gauge number 18 holds no relevance to the actual measurements.
The thickness of sheet metals is specified by gauge.
These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes.
8 gauge 4 176 mm stainless steel.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
For different materials of steel the same gauge will also correspond to different mm.
