In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., 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.
There are several errors in the thickness and tolerance charts. e.g. the nominal thickness for stainless steel 16ga sheet should be .0625". The thickness ranges is the tolerance chart do not line up properly with the gauge column and the values are not in agreement with the thickness chart.
A larger number indicates a longer nail, shown in the table below. Diameter of the nail also varies based on penny size, depending on nail type. Nails under 1 + 1 ⁄ 4 inch, often called brads, are sold mostly in small packages with only a length designation or with length and wire gauge designations; for example, 1″ 18 ga. or 3 ⁄ 4 ″ 16 ga.
The Birmingham gauge ranges from 5/0 or 00000, the lowest gauge number corresponding to the largest size of 0.500 inches (12.7 mm), to 36, the highest gauge number corresponding to the smallest size of 0.004 inches (0.10 mm). The increments between gauge sizes are not linear and vary. [2]
No. 7/0, the largest size, is 0.50 in. (500 thou or 12.7 mm) dia., No. 1 is 0.30 in. ( 300 thou ), and the smallest, No. 50, is 0.001 in. ( 1 thou or 25.4 µm ). The system as a whole approximates an exponential curve , plotting diameter against gauge-number (each size is a approximately a constant multiple of the previous size).

Between each step the diameter, or thickness, diminishes by 10.557%, and the area and weight diminish by ~ 20%. None of the above systems of measurement is part of the metric system. The current British Standard for metallic materials including wire is BS 6722:1986, which is a solely metric standard, superseding 3737:1964, which used the SWG ...
In much of the world wire diameter is often expressed in millimeters. For making jump rings, 10- to 18-gauge wire (2.5 to 1.3 mm) is used. Bracelet and necklace wire components are generally made out of wire that is 16-, 18- or 20-gauge (1.3 to 0.8 mm). Earring wires are usually made out of 18- or 20-gauge wire (1.0 to 0.8 mm).
