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] At higher gauge numbers, the increment between the two ...
A standard wire gauge. The British Standard Wire Gauge, often referred to as the Standard Wire Gauge or simply SWG, is a unit used to denote wire gauge (size) as defined by BS 3737:1964, a standard that has since been withdrawn. It is also known as the Imperial Wire Gauge or British Standard Gauge. Although its use has significantly declined ...
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.
(E.g. 1 mm diameter wire is ≈18 AWG, 2 mm diameter wire is ≈12 AWG, and 4 mm diameter wire is ≈6 AWG.) This quadruples the cross-sectional area and conductance. A decrease of ten gauge numbers (E.g. from 24 AWG to 14 AWG) multiplies the area, weight, and conductance by approximately 10.

If the difference between the two gauges is large enough – for example between 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge and 3 ft 6 in (1,067 mm) – three-rail dual-gauge is possible, but if not – for example between 3 ft 6 in (1,067 mm) and 1,000 mm (3 ft 3 + 3 ⁄ 8 in) metre gauge – four rails must be used. Dual-gauge rail lines ...
The circular forms of wire gauge measurement devices are the most popular, and are generally 3 + 3 ⁄ 4 inches (95 mm) in diameter, with thirty-six notches; many have the decimal equivalents of the sizes stamped on the back. Oblong plates are similarly notched. Rolling mill gauges are also oblong in form.
