E stands for energy, M for mass, C is the speed of light the 2 is the exponent of C.
The whole thing reads Energy equals mass time the speed of light squared. Einstein's theory of relativity.

Careful. The other answers you received are OK, but need some clarification. The m in E=mc^2 should really have been "delta m" or "change in mass." For example, when a radioactive particle decays into something else, the product has a slightly smaller mass than the original. Energy appears in its place. The change in mass, times the speed of light squared, equals the amount of energy that is formed.
So m isn't mass...it's change in mass.

Energy = Mass x the (speed of light)squared
Energy = Mass x 8.988 Ã 10^16 m^2 / s^2

Energy=Mass(Speed of Light Squared)
So energy equals mass times the speed of light squared.

It is mass energy equivalence formula. What everyone said is correct.
With the concept of mass-energy equivalence, we combine together the conservation of mass and the conservation of energy, allowing mass to be converted to forms of active energy (such as kinetic energy, heat or light) while still retaining mass. (However, if the system is not closed, such energy can be lost along with its associated mass.) Conversely, active energy in the form of kinetic energy or radiation can be converted to particles which have rest mass. The total amount of mass and energy in a closed system (as seen by a single observer) remains constant. Energy cannot be created or destroyed, and in all of its forms, trapped energy exhibits mass. In relativity theory, mass and energy are two forms of the same thing, and neither one appears without the other.

E=energy
M=mass
C=speed of light
2= squared (multiply a number by itself)
Energy=Mass * Speed of light (squared)

E (the energy in an atom or material) = M (mass of the atom or material) * C*C(C = speed of light)
Most materials cannot use all this energy. You can see this energy in a nuclear bomb.
