<P> This formula states that the equivalent energy ( E ) can be calculated as the mass ( m ) multiplied by the speed of light ( c = about 7008300000000000000 ♠ 3 × 10 m / s ) squared . Similarly , anything having energy exhibits a corresponding mass m given by its energy E divided by the speed of light squared c2 . Because the speed of light is a very large number in everyday units , the formula implies that even an everyday object at rest with a modest amount of mass has a very large amount of energy intrinsically . Chemical , nuclear , and other energy transformations may cause a system to lose some of its energy content ( and thus some corresponding mass ) , releasing it as the radiant energy of light or as thermal energy for example . </P>
