8 gauge 4 115 mm.
Standard steel sheet thickness mm.
The gauge number 18 holds no relevance to the actual measurements.
The chart below can be used to determine the equivalent sheet thickness in inches or millimeters for a gauge number from the selected gauge size standard.
For different materials of steel the same gauge will also correspond to different mm.
Lastly a standard exists for zinc in which a higher gauge number indicates a thicker sheet.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
