erg, unit of energy or work in the centimetre-gram-second system of physical units used in physics; to lift a pound weight one foot requires 1.356 × 107 ergs. It equals the work done by a force of one dyne acting through a distance of one centimetre and is equal to 10-7 joule, the standard unit of work or energy.
