1 Joule = 10^7 ergs.
Explanation:
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.
One Newton in turn is that force which produces in an object of 1 kg an acceleration of 1 m/s².
1 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.
And one dyne is that force which produces an acceleration of 1 cm/s² in an object of 1 gm.
So one erg = 1 gm × 1 cm/s² × 1 cm.
So 1 Newton = 1 kg × 1 m/s² = 1000 gm × 100 cm/s² = 10^5 dyne.
1 Joule = 1 Newton × 1 m displacement = 10 ^5 dyne × 100 cm displacement = 10^7 ergs.
