Wire and Sheet Gauge Conversion Chart

Sheet sheet or wire thickness is specified by gauge. The table below shows the actual thickness of sheet steel and wire in millimeters and inches compared to gauge sizes. These dimensions vary slightly between different materials such as stainless steel and aluminum – but should be accurate enough for most everyday purposes.
