Question

Find the ratio of CGS to SI unit of energy?

Answer 1

your answer

SI unit of energy is Joule which is derived from the units of force and distance.

Therefore 1 Joule= 1Nm

The CGS unit of energy is erg, where 1 Joule=10^7 erg.

In order to find the ratio, one should divide the two:

1erg/1Joule= 1/(10^7) = 10^(-7)

 The ratio is a unit-less quantity and remains constant.
