Why does E=mc²?

I think we can all agree that 1=1 but how can you say that E=mc². No one would say the E is the same letter as m.
One example I'd like to make is that NaCl=Na+ + Cl-
But in chemistry you do not use the equals sign you use arrows that indicate a process of conversion which is reversible.
Just as the conversion from energy to mass.

    May 19 2013: E = mc^2 does not imply that mass may be converted to energy but it allows for matter to be converted to energy. Mass and matter are not exactly the same. E = mc^2 essentially states that all energy is mass and vice verse.
