The centimetre-gram-second system was developed in the 2nd half of the 19th
century, with large input from the British Association for the Advancement
of Science. It was the extension of the orignal metric system to cover
units in physics beyond length, area, volume, and mass. It satisfied
physicists, but engineers found the units to be ridiculously small. In
1901 G. Giordi proposed a system based on metre, kilogram, second, and an
electrical unit, which in 1950 was chosen to be the ampere. In 1961 this
system was given the name of International système d'unités or SI.
centimetre-gram-second system SI (metre-kilogram-second-ampere)
----------------------------- ---------------------------------
centimetre metre
gram kilogram
abcoulomb = 10 C statcoulomb = 334 pC coulomb
abampere = 10 A statampere = 334 pA ampere
abvolt = 10 nV statvolt = 300 V volt
abohm = 1 n� statohm = 899 G� ohm
abfarad = 1 GF statfarad = 1.113 pF farad
abhenry = 1 nH stathenry = 899 GH henry
faraday = 96.5 kC coulomb
franklin = 334 pC coulomb
gauss = 0.1 mT tesla
maxwell = 10 nWb weber
oersted = 79.6 A/m amperes per metre
calorie = 4.19 J joule
Calorie = 4.19 kJ joule
erg = 0.1 µJ joule
dyne = 10 µN newton
kilogram-force = 9.807 N newton
ångström = 0.1 nm metre
fermi = 1 fm metre
The kiloogrtam-force is not cgs, but it is not SI either
