How do I calculate E=mc2?
You have to calculate c2 first, which is the speed of light times itself. c2 is 20043671E+12 meters per second. “E+12” means there are 12 zeroes after the number.
Then you need the “m”. “m” stands for the mass, in kilograms. “mc2” together means “m” times 20043671E+12.
So then you have the energy (in joules). If something had a mass of one kilogram, then it could be converted into 20043671E+12 joules of energy.

How is E=mc2 so destructive?
With this astonishing new formula that Einstein came up with, German scientists saw this as a weapon and started making one right away.
Einstein was afraid of what Germany might do if they were the first to make one of these atomic weapons, and he wrote a desperate letter to the president asking him to make these atomic bombs.
That was how World War II was fought. With atomic bombs based off Einstein’s formula E=mc2.

Was Einstein the first to think of E=mc2?
In fact, no. Einstein hadn’t. Hasenöhrl was the first to think of this equation, but he did it slightly incorrect. His equation was “E = 3/8c2”.
Another scientist thought that atoms interacted with their own fields: “E0 = 3/4mc2”.
The world would never have came up with a correct equation for special relativity if Albert Einstein hadn’t come up and said “E=mc2”.

Conclusion
So in conclusion, E=mc2 explains how much energy an object can produce, thus leading to the atomic bomb.
Yes, E=mc2 has become so famous over the years that eventually it has become a symbol of math. It hasn’t become any easier to understand, though.
