An erg is the unit of energy and mechanical work in the centimetre-gram-second (CGS) system of units, symbol "erg". Its name is derived from the Greek word meaning "work".

The erg is a small unit, equal to a force of one dyne exerted for a distance of one centimeter. In the CGS base units, it is equal to one gram centimeter-squared per second squared (g·cm²/s²). It is thus equal to 1 × 10⁻⁷ joules or 0.1 microjoule (µJ) in SI units.

1 erg = 10⁻⁷ joule

1 joule = 10⁷ erg

1 dyn cm = 1 erg.
