The erg conversion selector selects the energy measurement unit to convert to starting from ergs (erg). To make a conversion starting from a unit of energy other than erg, simply click on the "Reset" button.
The erg is a unit of energy or work in the centimetre-gram-second (CGS) system of units equal to 10-7 joules (1 erg = 10-7 J), the SI derived unit of energy.
The erg (erg) is also equal to 100 nanojoules (nJ), or 10-10 kilojoules (kJ), or 7.375622 × 10-8 foot-pound force (ft-lbf), or 2.373036 × 10-6 foot-poundal (ft-pdl), or 8.850746 × 10-7 inch-pound force (in-lbf) or 2.777778 × 10-14 kilowatt hours (kWh).
The erg is the work done when a force of one dyne acts over a distance of one centimeter.
1 erg = 1 dyn × 1 cm
The dyne (dyn) is a unit of force in the centimetre-gram-second (CGS) system of units while the centimeter (cm) is a unit of length in the SI.
