# unit and dimension

Asked by 3rd May 2010, 11:43 AM

Dear student,

The unit of power in CGS system is erg. 1 erg equals 1 dyne force moved through 1 cm in one second, whereas unit of power in MKS system is Watt. 1 Watt equals one Newton of force moved through one meter in one second.

In MKS unit, energy is measured in Joules. If 1 Newton of force moved through 1 meter, then the work done is 1 Joule. If it is done in one second then the power is 1 Watt. It may take some time for novice to assimilate this concept.

1 earg = 10^-7 Watts therefore, 100 W = 10 -5 erg

Hope this helps.
