The equation explains the the amount of energy that will be released when a given amount of matter or mass is converted into pure energy.

So E (energy) = Mass (the given amount) multiplied by the Speed of Light Squared.

I've always thought that this equation resembles the inverse square law run backwards.

This equation is surprising to scientists because of the extremely LARGE number that occurs for the letter "E" (energy). The mass of an object times 186,000 and times 186000 again equals a really BIG number for energy. It shows the amount of atomic energy in any small object.

E = mc^2 is the equation which made Einstein famous. It has a greater significance. It solved many problems associated with the universe. It led to the invention of atomic bomb.

E - Energy

m - Mass

c - Speed of the light

It means that a particular amount of mass can be converted into energy and vice versa. Energy released during this conversion is equivalent to the mass of the object multiplied with square of the speed of light.

If we consider mass of hydrogen atoms in a glass of 1 litre water, it is sums up to 111 grams. If we want to convert this small mass into energy,

E = 0.111(Kg) * c^2 which is really huge amount of energy.
