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

Energy: Energy is a fundamental quantity that every physical system possesses. Energy of physical system in a certain given state is defined as the amount of work W needed to change the state of the system from some initial state (called reference state or reference level) to the given state....

Mechanical work: Work (abbreviated W) is the energy transferred by a force to a moving object. Work is a scalar quantity, but it can be positive or negative. It is associated with a change in energy, but not all changes in energy can be readily analysed in terms of work....
