1 erg = 10^-7

S.I unit of work joule: kg.m. m/s.s.

C.G.S unit of work erg: g.cm.cm/s.s.

After deciding both we get 1Joule: 10*7.

10^3*10^2*10^2 = 10^7.

Kg into gm*meter into centimeter*meter into centimeter = 10^7.

Answer: There are 10 million ergs in 1 joule.

The erg is the unit of work done - or energy expended - in the centimeter-gram-second (CGS) system of measurement.

An erg is equal to .0000001 joule. A joule is the unit of work done - or energy expended - in the meter-kilogram-second (MKS) system.

A joule is a unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second.

AND

A joule is a unit of energy equal to the work done when a force of one newton acts through a distance of one meter.
