Erg \Erg\, n. [Gr. ? work.] (Physics) The unit of work or energy in the C. G. S. system, being the amount of work done by a dyne working through a distance of one centimeter; the amount of energy expended in moving a body one centimeter against a force of one dyne (981 dynes exert the same force as a one gram mass in the earth's gravitational field). One foot pound is equal to 13,560,000 ergs. The absolute Joule is equivalent to 10^ 7 ergs, which are equivalent to 0.2389 gram-calories at 15[deg] C. See also mechanical equivalent of heat under equivalent.
Douglas Harper's Etymology Dictionary
unit of energy in the C.G.S. system, coined 1873 by the British Association for the Advancement of Science, from Greek ergon "work" (see organ).
"region of drifting sand dunes," 1875, from French erg (1854), from North African Arabic 'irj, from a Berber word.
Etymology 1 n. The unit of work or energy, being the amount of work done by a dyne working through a distance of one centimeter. Equal to 10−7 joules. Etymology 2
n. (context geomorphology English) A large desert region of sand dunes with little or no vegetation, especially in the Sahara.
n. a cgs unit of work or energy; the work done by a force of one dyne acting over a distance of one centimeter
The erg is a unit of energy and work equal to 10 joules. It originated in the centimetre–gram–second (CGS) system of units. It has the symbol erg. The erg is not an SI unit. Its name is derived from ergon (’έργον) a Greek word meaning work or task.
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·cm/s). It is thus equal to 10 joules or 100 nanojoules ( nJ) in SI units. An erg is approximately the amount of work done (or energy consumed) by one common house fly performing one "push up", the leg-bending dip that brings its mouth to the surface on which it stands and back up.
1 erg = 10 J = 100 nJ
1 erg = 10sn·m = 100 psn·m = 100 pico sthène-metres
1 erg = 624.15 GeV =
1 erg = 1 dyne cm = 1 g·cm/s
An erg is a unit of energy.

Erg is a fictional mutant character appearing in American comic books published by Marvel Comics.
ERG'' (ETS-related gene'') is an oncogene. ERG is a member of the ETS (erythroblast transformation-specific) family of transcription factors. The ERG gene encodes for a protein, also called ERG, that functions as a transcriptional regulator. Genes in the ETS family regulate embryonic development, cell proliferation, differentiation, angiogenesis, inflammation, and apoptosis.
Erg was a vessel built and owned by Halifax Steamship Ltd. in 1915. She was used to ferry workers across the harbour to vessels under repair during the Second World War. Erg was sunk in the Halifax Harbour three times and is currently located in the Bedford Basin.
An erg (also sand sea or dune sea, or sand sheet if it lacks dunes) is a broad, flat area of desert covered with wind-swept sand with little or no vegetative cover. The term takes its name from the Arabic word ʿarq , meaning "dune field". Strictly speaking, an erg is defined as a desert area that contains more than of aeolian or wind-blown sand and where sand covers more than 20% of the surface. Smaller areas are known as "dune fields". The largest hot desert in the world, the Sahara, covers and contains several ergs, such as the Chech Erg and the Issaouane Erg in Algeria. Approximately 85% of all the Earth's mobile sand is found in ergs that are greater than . Ergs are also found on other celestial bodies, such as Venus, Mars, and Saturn's moon Titan.
Usage examples of "erg".
Nisa Greet, a young astronavigator on her first Cosmic expedition, held her breath as she watched Erg Noor in silence, and the commander himself seemed oblivious of everything but his work.
The only thing that troubled her was the thought that others were having a harder time, especially Erg Noor.
Her flashing hazel eyes, framed in dark rings, were stealthily following Erg Noor as he took his place at the instrument panels after a refreshing wave bath and a good meal.
Briefly Erg Noor explained the mathematical basis for the destructive change that takes place in matter when it approaches the speed of light, but he noticed that the girl was not paying any great attention to him.
He kept looking at the control-tower door expecting Erg Noor to appear with his usual rapid movements although he knew that the awakening from prolonged sleep is a lengthy process.
Veda was in love with Erg Noor, Member of the Astronautical Council and Commander of Cosmic Expedition No.
Once it succeeded but Erg Noor managed to catch hold of Eon Thai as he rolled past, dropped flat on his stomach and caught hold of a big boulder with his hooked gloves.
In addition to these things Erg Noor considered it necessary to take some of the personal belongings of the lost crew so that, after a thorough disinfection, they could be taken to Earth for the relatives of the dead people to keep in their memory.
Sticky with perspiration from head to foot, Erg Noor, with no will of his own, strode towards the black gap in the darkness.
It bent forward like the stem of a plant and clearly intended leaning over the protective field to get Erg Noor.
Although nobody had been hurt Erg Noor decided that they had had enough.
At last Erg Noor, divested of his heavy spacesuit, was able to enter his ship or rather to crawl in under the influence of the gravity of the fearful planet.
This time there were four instead of the three people awake on board: Erg Noor and Pour Hyss, whose tour of duty it was, were joined by Louma Lasvy and Eon Thai.
Carried away by the pictures passing before his eyes, Erg Noor did not think of that immediately.
Everything moves and develops in a spiral and Erg Noor could see in his imagination that magnificent spiral of the common ascent as applied to life and to human society.
