Gauss (Gs) is the unit for magnetic flux density. It is given in centimeter-gram-seconds and corresponds to one Maxwell per square centimeter. In air, one Gauss corresponds to a field strength of one Oersted (Oe). There is also a connection with Tesla, according to which one Gauss is `10^-4` Tesla or `10^5` Gamma.
The Gauss is named after the German mathematician and astronomer Karl Friedrich Gauss (1777 to 1855), who became famous by many theories of algebra, differential geometry and probability calculus.
