### erg

(CGS unit of energy)

The **erg** is a CGS unit of energy equivalent to
the work done by the force of a **dyne** (a unit
of force) pushing over a centimeter distance, i.e.,
one gram centimeter-squared per second-squared
(g·cm²/s²).
10^{7} ergs make a joule.
*Erg* remains widely used in astrophysics, as is the CGS
system generally.
