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". Work (abbreviated W) is defined as the line integral of a scalar product of force and displacement vectors (see below). ... This article or section is in need of attention from an expert on the subject. ... The definition, agreement and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day. ...
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-square centimeter per second squared (g·cm2/s2). It is thus equal to 1 × 10-7 joules or 0.1 microjoule (µJ) in SI units. It is approximately the amount of energy that a mosquito uses to take flight. In physics, the dyne is a unit of force specified in the centimetre-gram-second (cgs) system of units, symbol dyn. One dyne is equal to exactly 10-5 newtons. ...

Late last month, The Australian reported that the government's contract with ERG could be revised for a third time after the company revealed that it would miss a deadline to repay its creditor $49.7 million.
ERG and the state government have twice changed the agreement to supply Sydney with Tcard, a contactless smartcard ticketing system.
The government announced 10 years ago it would implement a cashless public transport ticketing system, known as the Tcard, which it had hoped would be in place for the 2000 Olympic Games.
