ergErg (en)
Definition
- 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 ergon, meaning 'work'. An erg is the amount of work done by 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 ($g \\cdot cm^2/s^2$). It is thus equal to $10^{-7}$ joules or 100 nanojoules in SI units. $1 erg = 10^{-7} J = 100 nJ$, $1 erg = 624.15 GeV = 6.2415 \ imes 10^{11} eV$, $1 erg = 1 dyne\\cdot cm = 1 g \\cdot cm^2/s^2$.
