Aluminum gauge, commonly referred to as the “gauge” o te aluminum, is a measurement of the thickness or diameter of aluminum sheet or wire. It is a common method of specifying the thickness of aluminum materials and is used in a variety of industries, including construction, manufacturing, and metalworking.

In the United States, aluminum specifications are usually expressed in numerical values, ranging from lower numbers to higher numbers. The higher the gauge number, the thinner the aluminum sheet or wire. Conversely, lower gauge numbers indicate thicker aluminum material. Ei hi'oraa:
12 gauge aluminum is thicker than 16 gauge aluminum.
18 gauge aluminum is thinner than 14 gauge aluminum.

What is the thickness indicated by the aluminum gauge? Take a 12 gauge aluminum sheet as an example. How many inches is 12 gauge aluminum?
The thickness of 12 gauge aluminum plate is approximately 0.0808 inches or 2.05 Te mau mana'o tauturu no te.
