When working with sheet metal, it’s important to understand gauges. The gauge of sheet metal refers to its thickness. It’s important to know the gauge for your project to ensure you’re using the correct thickness of metal.
However, a gauge number doesn’t directly tell you the thickness in millimeters (mm) or inches. That’s where a gauge in mm chart comes in handy. These charts allow you to quickly convert between gauge numbers and actual measurements.
Keep in mind that different materials, like steel and aluminum, may have slightly different thicknesses for the same gauge number.
