Is Charge-Energy Conversion More Energetic Than Mass-Energy Conversion?

In this article, we derive the relation between energy and charge in the form of charge-energy equivalence using gauge-gravity duality and special relativity. In comparison with Einstein's energy-mass equivalence, our result shows that the conversion of charge into energy leads to more energy gain than the conversion of mass into energy. The result also shows that the energy increases with the increase of charge. For our result, the energy also depends on the Newton's gravitational constant.
