The erg is a unit of energy equal to 10 −7 joules (100 nJ). It is not an SI unit , instead originating from the centimetre–gram–second system of units (CGS). Its name is derived from ergon ( ἔργον ), a Greek word meaning 'work' or 'task'.

What is the unit called an erg? The unit of work in the centimeter-gram-second absolute system of units, 1 erg being the work done by a force of 1 dyne acting through a distance of 1 centimeter, = 10⁻⁷ joules. Symbol, erg. A million ergs was sometimes termed a megalerg.

What is the relation between commercial and SI unit of energy? The commercial unit of energy is 1 kWh. One kilowatt-hour is defined as the amount of energy consumed by a device in one working hour at a constant rate of one kilowatt.

SI unit: joule. The SI derived unit for energy is the joule. 1 joule is equal to 10000000 erg.

Apr 26, 2024 · A joule is the SI unit of energy, representing the amount of work done when a force of one newton is applied over a meter, while an erg is a much smaller unit, used in the CGS system, equal to 10^-7 joules.

erg; Unit of: Energy and power; Definition: One erg is equal to the work done by a force of one dyne, when its point of application moves 1cm in the direction of action. Origin: In 1873, a committee of the BAAS recommended the name erg or ergon for the C.G.S. unit of energy. Common references:

May 31, 2023 · One erg is the amount of work done by a force of one dyne exerted for a distance of one centimeter. In terms of SI units, the erg is defined as follows: where the joule is the SI unit for energy.
