The gauss, symbol G, sometimes Gs, is the cgs unit of measurement of magnetic flux density (or "magnetic induction") (B). It was named after German mathematician and physicist Carl Friedrich Gauss in 1936. One gauss is defined as one maxwell per square centimeter. The cgs system has been superseded by the International System of Units (SI), which uses the tesla (symbol T) as the unit of magnetic flux density. One gauss equals 1×10−4 tesla (100 μT), so 1 tesla = 10,000 gauss.
