Gauss (unit)

The gauss, abbreviated as G or Gs, is the cgs unit of measurement of a magnetic field B, which is also known as the "magnetic flux density" or the "magnetic induction". It is named after German mathematician and physicist Carl Friedrich Gauss. One gauss is defined as one maxwell per square centimeter. The cgs system has been formally superseded by the SI system, which uses the tesla (T) as the unit for B. One gauss equals 1×10−4 tesla (100 μT).
Unit name and convention
As with all units whose names are derived from a person's name, the first letter of its symbol is uppercase ("G"), but when the unit is spelled out, it should always be written in lowercase ("gauss"), unless it begins a sentence.
Unit conversions
According to the system of Gaussian units (cgs), the gauss is the unit of magnetic flux density B and the equivalent of esu/cm2, while the oersted is the unit of magnetizing field H...
