Abstract
The CGS system had the disadvantage that many of the units were of inconvenient size, and in order to avoid the use in everyday life of factors involving high powers of ten, scientists defined some practical units for electricity—ampere, volt, watt, ohm, henry, farad etc. They omitted, however, to do likewise for magnetism, and continued to use CGS units for magnetic flux and magnetomotive force. Moreover, although they measured current in amperes, they retained the electrostatic CGS unit for charge.Keywords
