Magnetic fields, or more specifically, magnetic flux densities historically have been measured with a unit called the milligauss – 1 milligauss(mg) being equal to 0.001 Gauss(g). Electrical engineers and physicists use the Tesla as a unit of international standard, one Tesla being the equivalent to 10,000 Gauss or 10,000,000 milligauss. Typically the Tesla is used in technical journals and the milligauss unit is used in information for the general public.
