Erg 9877 223340392 2008-07-03T17:25:51Z Bkell 32452 the E in E=mc^2 stands for energy, not ergs (energy can be measured in any unit) {{otheruses}} An '''erg''' is the unit of [[energy]] and [[mechanical work]] in the ''[[Centimetre gram second system of units|centimetre-gram-second]]'' (CGS) system of [[Units of measurement|unit]]s, symbol "erg". Its name is derived from the [[Greek language|Greek]] ''ergon'' meaning work <nowiki>[</nowiki>[[Oxford English Dictionary|OED]]<nowiki>]</nowiki>. The erg is a small unit, equal to a force of one [[dyne]] exerted for a distance of one [[centimetre]]. In the CGS [[Unit of measurement#Base and derived units|base units]], it is equal to one [[gram]] centimetre-squared per [[second]] squared (g·cm²/s²). It is thus equal to [[1 E-7 J|1 &times; 10<sup>−7</sup> joule]]s or 100 nanojoule (nJ) in [[SI]] units. 1 erg = 10<sup>−7</sup> [[joule]] 1 erg = 6.2415 {{e|2}} GeV = 6.2415 {{e|11}} eV 1 joule = 10<sup>7</sup> erg 1 [[dyn]] cm = 1 erg. {{physics-stub}} [[Category:Units of energy]] [[Category:Centimetre gram second system of units]] [[be-x-old:Эрг]] [[da:Erg (måleenhed)]] [[de:Erg (Einheit)]] [[es:Ergio]] [[eo:Ergo]] [[eu:Erg]] [[fa:ارگ (یکا)]] [[fr:Erg (unité)]] [[it:Erg]] [[he:ארג]] [[nl:Erg]] [[ja:エルグ]] [[pl:Erg (jednostka)]] [[pt:Erg]] [[ru:Эрг]] [[sl:Erg]] [[fi:Ergi]] [[sv:Erg]] [[tr:Erg]] [[uk:Ерг]] [[zh:爾格]]
