Wire gauge is a measurement of wire diameter. This determines the amount of electric current the wire can safely carry, as well as its electrical resistance and weight . Types of wire gauge
A table of the gauge numbers and wire diameters is shown below. [ 1 ] [ 2 ] The basis of the system is the thou (or mil in US English), or 0.001 in . Sizes are specified as wire diameters, stated in thou and tenths of a thou (mils and tenths).
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 also the best-known gauge worldwide; 55% of the world uses this track. In 2020, China’s rail network is standard gauge, with around 79,685 km (49,514 mi) of line. [92] 1,440 mm 4 ft 8 + 11 ⁄ 16 in: Switzerland
The chain of traceability allows any measurement to be referenced to higher levels of measurements back to the original definition of the unit. [ 2 ] Traceability is obtained directly through calibration , establishing the relationship between an indication on a standard traceable measuring instrument and the value of the comparator (or ...
Gauge block, a metal or ceramic block of precisely known dimension, used in measuring; Sight glass, also known as a water gauge, for measuring liquid level heights in storage tanks and pressure vessels; Boost gauge, a gauge used in conjunction with turbo-super-chargers; Pressure gauge or vacuum gauge, see pressure measurement
The chain is still used in agriculture: measuring wheels with a circumference of 0.1 chain (diameter ≈ 2.1 ft or 64 cm) are still readily available in Canada and the United States. For a rectangular tract, multiplying the number of turns of a chain wheel for each of two adjacent sides and dividing by 1,000 gives the area in acres.
This conversion is indirect and happens in two stages. Through a mechanical arrangement, the torque being sensed deforms a strain gauge. The strain gauge converts the deformation to electrical signals. A torque transducer usually consists of four strain gauges in a Wheatstone bridge configuration. Torque transducers of one or two strain gauges ...
