The CGS
(Centimeter-Gram-Second) system was used exclusively for
many years as the basis for all magnetic measurements.
In
recent years the SI (System International) or MKS
(Meter-Kilogram-Second) system has been proposed as the
only method used and is the preferred method in most
colleges and universities.
Industry still tends to stay
with the CGS system.
