The SISystem uses Meter (m), Kilogram (Kilogramme)(kg)
and
Second (s) as basic units.
It is also named MKS
 System (or the
MKSASystem).
The CGS System uses Centimeter, Gram, Second as basic units.
The attached physical units for both systems are length, mass and time.
Further basic units for the SI System are Ampère (A),
with the attached physical unit electric
current,
the Lichtstärke
(light strength) Candela
(cd),
the Temperature
Kelvin
(K)
and the Stoffmenge
(quantity of material) Mol
(mol).
