The unit of magnetic induction in the cgs system, 10-4 tesla. Also known as the abtesla.

The earth’s average magnetic field strength is approximately 0.3 - 0.7 G.

Named for Karl Friedrich Gauss, the great German mathematician and astronomer.

A long straight wire carrying 100 Amp produces a magnetic field of 10 G (0.001 T) at a distance of 2 cm from the wire.

kilogauss (kGs)

Equal to 1000 gauss or 0.1 tesla.

milligauss (mG)

Equal to 0.001 gauss, 0.1 microtesla, or 100 nanoteslas.

The magnetic fields generated by power lines and electronic equipment are often measured in milligauss.
