The units for magnetic flux Φ, which is the integral of magnetic B-field over an area, are the weber (Wb) in the SI and the maxwell (Mx) in the CGS-Gaussian system. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted. The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx/cm 2 or g/ Bi/s 2, while the oersted is the unit of H-field. : 147–148 The gauss may be combined with metric prefixes, : 128 such as in milligauss, mG (or mGs), or kilogauss, kG or kGs.ġ G = M x ⋅ c m − 2 = g B i ⋅ s 2 ≘ 10 − 4 T = 10 − 4 k g A ⋅ s 2 When the unit is spelled out, it is written in lowercase ("gauss"), unless it begins a sentence. Since the name is derived from a person's name, its symbol is the uppercase letter G. Name, symbol, and metric prefixes Īlbeit not a component of the International System of Units, the usage of the gauss generally follows the rules for SI units. The SI unit for magnetic flux density is the tesla (symbol T), which corresponds to 10,000 gauss. One gauss is defined as one maxwell per square centimetre.Īs the centimetre–gram–second system of units (cgs system) has been superseded by the International System of Units (SI), the use of the gauss has been deprecated by the standards bodies, but is still regularly used in various subfields of science. It was named after the German mathematician and physicist Carl Friedrich Gauss in 1936. The unit is part of the Gaussian system of units, which inherited it from the older centimetre–gram–second electromagnetic units (CGS-EMU) system. The gauss (symbol: G, sometimes Gs), is a unit of measurement of magnetic induction, also known as magnetic flux density.
