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]
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or simply SWG, is a unit used to denote wire gauge (size) as defined by BS 3737:1964, a standard that has since been withdrawn.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 ...
American wire gauge is used for most metal wire. Scoop (utensil) sizes, numbered by scoops per quart; Thickness of leather is measured in ounces, 1 oz equals 1 ⁄ 64 inch (0.40 mm). [30] Bolts and screws follow the Unified Thread Standard rather than the ISO metric screw thread standard.
By definition, 36 AWG is 0.005 inches in diameter, and 0000 AWG is 0.46 inches in diameter. The ratio of these diameters is 1:92, and there are 40 gauge sizes from 36 to 0000, or 39 steps. Because each successive gauge number increases cross sectional area by a constant multiple, diameters vary geometrically.
Standard gauge is defined both in metric and in imperial units. It is the most widely-used gauge worldwide, ab out 60% of the world uses this track.

In Western Australia, the narrow-gauge iron ore railways serving Geraldton port and the new port at Oakajee will be designed for ease of conversion to standard gauge. [5] [needs update] 1,435 mm (4 ft 8 + 1 ⁄ 2 in) 1,600 mm (5 ft 3 in) 2016–present Australia Victoria
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. Gauge differs between ferrous metals and nonferrous metals such as aluminum or copper. Copper ...
Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
