Aluminum Sheet Gauge Conversion Chart

Unlike inches and mm, there is no conversion formula for Ga. Even if non-ferrous metal plates and steel plates are of the same gauge, the thickness is actually different. If you need to know the conversion between the gauge and inch, mm of the aluminum plate, you can find the corresponding values in the table below.
