This principle shows that mass and energy are mutually convertible under certain conditions. Thus, when a certain amount of matter is converted into energy, the energy obtained is equal to the product of mass and square of the velocity of light,18 and similarly when an amount of energy is converted into matter, the mass produced is given by the energy divided by the square of the velocity of light.
An illustration will clarify the relation: Suppose that one kilogram of coal is totally converted into energy; then the energy obtained would be equivalent to 25 billion kilo-watt-hour of electricity.
As a result of this new discovery, the two independent laws of conservation of mass, and that of energy, have been united to form a single law of conservation of mass and energy, enunciating that the sum total of energy and mass x c2 (where c-velocity of light) is constant for any system and cannot increase or decrease. Thus the massenergy equivalence establishes the universal fact that mass and energy are essentially the forms of the same entity.

The chief merit of the mass-energy relation lies in the fact that it is experimentally verified for all types of energy. The most prominent verification is found in the discovery of the atom-bomb.
