  (ûrg) pronunciation
n.

The centimeter-gram-second unit of energy or work equal to the work done by a force of one dyne acting over a distance of one centimeter.

[From Greek ergon, work.]


 
 

A unit of energy in the CGS system. It is equal to .0000001 joule in the MKS system. See CGS system.



 

[Etymology: Gk: ‘work’] energy, work, quantity of heat Metric-c.g.s. Identically dyne·centimetre, i.e. work done by 1 dyne acting over 1 centimetre, = 10-7 J (= cm2·g·s-2 in c.g.s. base terms). Erg can be prefixed, as in cerg = centierg.

 
(ûrg) , unit of work or energy in the cgs system of units, which is based on the metric system; it is the work done or energy expended by a force of 1 dyne acting through a distance of 1 centimeter. In terms of the joule, the unit of work or energy in the mks system, 1 erg equals 0.0000001 joule.

For other uses see Erg (disambiguation)

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 small unit, equal to 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·cm²/s²). It is thus equal to 1 × 10-7 joules or 0.1 microjoule (µJ) in SI units.

1 erg = 10-7 joule

1 joule = 107 ergs

From Greek ergon work [OED]
