Answer 2

Erg is not an SI unit.

• It is the CGS (centimeter-gram-second) unit of energy.
• Erg is derived from the Greek word 'ergon' which means 'work' or 'task'.
• 1 erg = $10^{-7}$ joules
• An erg is the amount of energy expended or the work done by one dyne of force to move a body along a one-centimeter distance.
• 1 erg = 1 dyne x 1 cm
• In CGS base units 1 erg = 1 $g.cm^{2}. s^{-2}$
