The thickness of sheet metals is specified by gauge.
Steel sheet gauge to mm.
8 gauge 4 176 mm stainless steel.
This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.
These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes.
8 gauge 4 115 mm.
0 0315 inch 22 gauge.
The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size.
8 gauge 4 191 mm aluminum brass copper.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.
Our standard sizes are 0 8mm.
For different materials of steel the same gauge will also correspond to different mm.
