E=mc2: As Famous as the Man Who Wrote It | AMNH
WEBEinstein's equation shows that mass and energy are equivalent—so long as you multiply by the "conversion factor" of c 2 (the speed of light multiplied by itself). This factor is huge: 90 billion kilometers 2 per second 2. So if you multiply a small amount of mass—say, the mass of a penny—by c 2, you'll get a tremendous amount of energy.
