BWG - Birmingham Wire Gauge - Used to determine wall thickness of pipe - in gauge and decimal parts of inch; CM - Circular Mil Area - The circular mil area - CM - is a unit denoting the cross-sectional size of a wire or a cable; Drill Bits - Conversion Chart - Convert between drill bit dimensions - gauge numbers, inches and mm
Wire gauge is a measure for the size of a wire, either in diameter or in cross sectional area. Gauge and weight chart for sheet steel, galvanized steel, stainless steel, aluminum and strip & tubing: For full table with Stainless Steel, Aluminum, Strip and Tubing - rotate the screen!
The thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. Please note that ASTM states in specification ASTM A480-10a "The use of gage number is discouraged as being an archaic term of limited usefulness not having general agreement on meaning."
The US standard gauge system usually uses the value from 2, 1, 0, 2/0, 3/0, 4/0, 5/0, 6/0 or 7/0. MSG’s largest thickness in sheet steel is 3. In galvanized steel it is 8 and for stainless steel it is 6/0.
For example, 21Ga. corresponds to the standard steel thickness of 0.0329 inches (0.84mm); the corresponding galvanized steel thickness is 0.0366 inches (0.93mm), and the corresponding aluminum thickness is 0.028 inches (0.71mm).

Sheet Metal Guage Tolerances. During the rolling process the rollers bow slightly, which results in the sheets being thinner on the edges. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the Manufacturer's Standard Gauge, which has no inherent tolerances.
In the US, the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous (iron-based) metals and nonferrous metals such as aluminum or copper.
If using the U.S. Standard Gauge to determine metal gauge from metal thicknesses, 0.019 inch correlates to a 26-gauge metal thickness. However, if using B & S (Brown and Sharpe) gauge conversions, 26 gauge only is 0.0159 of an inch thick.
