About this calculator

The erg is the unit of energy in the CGS (centimetre-gram-second) system, defined as the work done by a force of one dyne acting over a distance of one centimetre. Because the SI system uses metres, kilograms and seconds instead, 1 erg equals exactly 10⁻⁷ joules — an erg is a tiny amount of energy, about what a mosquito uses to take off.

This calculator converts an energy value from ergs to joules and to calories, which is useful whenever older physics texts, spectroscopy data, or astrophysical papers quote energies in CGS units and a modern SI or everyday figure is needed for comparison or further calculation.
