work = force x displacement
Force = 10 to the power 5 dyne
Displacement = 10 to the power 2dyne
Work= 10to the power 5 x 10 to the power 2
Work= 10 to the power 7 dyne

- erg is the CGS unit of work/energy
- Joule is the SI unit of work/energy.
Defination of Erg
- one erg is the work done when a force of one dyne produces a displacement of 1 cm in an object in the direction of the force.
1 erg = 1 gm × 1 cm/s² × 1 cm.
Defination of Joule
- one Joule is the work done by a force of 1 Newton in producing a displacement of 1 metre in an object in the direction of the force.
1 Newton = 1 kg × 1 m/s² = 1000 gm × 100 cm/s² = 10⁵ dyne.
1 Joule = 1 Newton × 1 m displacement = 10⁵ dyne × 100 cm displacement = 10⁷ ergs.
1 Joule = 10⁷ ergs
