When we convert a certain amount of mass to energy, only some amount is converted? So it will be against mass-energy relation..... Some mass get desipitated... Then how mass-energy relation will be true..

E = mc^2 is the thoeratical maximum energy a mass possess. This theory doesnt deal with convertablity of that energy. That is engineering. This equation is purely maths and physics

e=mc^2 applies to all the mass that is actually converted to energy. So the energy you get from a given amount of, say, uranium could be considered as e=fmc^2, where f is conversion efficiency, expressed as a fraction of 1.

I think you are wondering why uranium, for example, is not toally converted to energy.
It is because the total mass-energy of the nucleus is preserved. In other words, although some of the mass is converted to energy, most of it remains as it is, mass.

And E=mc^2 only applies to particles at rest. The true equation is E = (mc^2)/(1-(v^2)/c^2)^1/2

Hi. If you had a cord of wood and only burned one log...

If you do the math. (pay attention to dimensions when you do) you'll see that it works.
