Question

What is the relation between erg and Joule?

Answer 1

An erg is the amount of work done by a force of one dyne exerted for a distance of one centimeter. In the CGS base units, it is equal to one gram centimeter-squared per second-squared (g. cm2/s2). It is thus equal to 10−7 joules or 100 nanojoules (nJ) in SI units.
