Definition

CGS is the centimetre-gram-second standard system of units of measurement.


This system is rarely used nowadays, the SI units having largely taken over.


CGS Base Units

CGS base units
Name Unit symbol Dimension Symbol
centimetre $\mathrm{cm}$ Length $l$
gram $\mathrm g$ Mass $m$
second $\mathrm s$ Time $t$


CGS Derived Units

Dyne

The dyne is the CGS unit of force:

$1 \ \mathrm {dyn} = 1 \ \mathrm g \ \mathrm{cm} \ \mathrm s^{-2}$


Also known as

The CGS system is also known as the Gaussian system, for Carl Friedrich Gauss.

This term is used usually in the context of atomic physics and solid-state physics, where their scale is more convenient than that of SI units.
