The equation is spoken as follows - Energy equals mass times (multiplied by) the speed of light (186,000 miles per second) squared (multiplied by itself).

E stands for energy.
m stands for mass.
c stands for the speed of light (186,000 miles per second)
The units Einstein used for the speed of light were metric and I believe it was in centimeters, but that doesn't matter. What you do immediately see in the equation is that if you square the speed of light (186,000mi/sec times 186,000mi/sec) you get a very big number. So you get a lot of energy from even a little bit of mass when you start messing around with atomic nuclei. The most efficient energy (E) in the universe is when two protons (m) fuse together (c squared). Like in the sun or in a hydrogen bomb. Einstein figured out a way to quantify what happens in the core of the sun.

Energy equals mass converted times the speed of light squared. That is, when matter is changed into energy, the amount of energy is related the mass converted. The constant is the speed of light (approximately 300,000,000 meters per second), making the conversion factor 9.0 X 10e16 (9 followed by 16 zeros) with units of meters squared per second squared.
If a kilogram of matter is changed into energy (so, in a thermonuclear explosion), the energy is 9.0 X 10e16 joules. One joule is one kilogram-meter squared per second squared. This is an enormous amount of energy. To put it into prospective, the amount of matter converted into energy in the Hiroshima atomic bomb explosion was a few pounds.

There is an equivalence between mass and energy.
If all the mass could be converted to energy, the amount of energy released is given by the formula E=mc^2 where c is the speed of light (approx. 300,000 km per sec or 186,000 miles per sec)

It tells u how mass and ability are interrelated.case in point this equation might want to easily advise that if 1kg of a substance is punctiliously burnt in one of those fashion that no skill is lost to the ambience then as in step with the experimental calculation by technique of Einstein it signifies that 9* 10^16 Joule of skill is liberated.So mass is a form of saved skill.

When a mass move near the speed of light, the mass can be converted into energy. For better and simple explanation visit http://www.dw-world.de/dw/0,2142,3062,00.html#

e=energy
m=mass
c=speed of light
c^2=speed of light x speed of light
