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or simply SWG, is a unit used to denote wire gauge (size) as defined by BS 3737:1964, a standard that has since been withdrawn.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 ...
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 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.
The Birmingham gauge is also known as the Stubs Iron Wire Gauge or Birmingham Wire Gauge and is distinct from the Stubs Steel Wire Gauge and the British Standard Wire Gauge. It is commonly referred to simply as gauge (abbreviated as G ), [ 3 ] but this should not be confused with the French gauge , a separate system used for measuring the outer ...
Any two successive gauges (e.g., A and B) have diameters whose ratio (dia. B ÷ dia. A) is (approximately 1.12293), while for gauges two steps apart (e.g., A, B, and C), the ratio of the C to A is about 1.12293 2 ≈ 1.26098. Similarly for gauges n steps apart the ratio of the first to last gauges is about 1.12293 n.
The next set of 3 digits gives the steel's minimum yield strength. So S355 has a minimum yield strength of 355 MPa for the smallest thickness range covered by the relevant standard – i.e. EN10025. [2] Below is a table indicating the most common application codes.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Generally, the system of gauge-and-inches is used: In gauge notation, jewelry less than 1 ⁄ 2 ″ thick is typically measured in a system originally devised for measuring wire thickness. A gauge number denotes a thickness on a standardized scale which, for most purposes, starts at 20g (0.812 mm thick— often used for the posts for nose studs ...
