Question

what is the ratio of si unit and CGS unit of electrical energy​

Answer 1

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
