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). 107 ergs make a joule. Erg remains widely used in astrophysics, as is the CGS system generally.
