No, nuclear fission does not convert mass into energy.
It releases binding energy of a nucleus.

To me so far, E=mc² is a conversion factor.
Conversion of Kg into Joules.

ok so nuclear reactions don't produce something from nothing but they however converting the electron positron pairs from neutrons that is something that resides in nucleus and the relation e=mc^2 is just a conversion factor to judge the energy of a body...!! can i say this by summing all..??

Here is a dumb thought.
Say, I have a ball in my hand of mass 1 Kg.
I throw it with speed 20m/sec.
Its kinetic energy is 200J. Mass equivalent of this energy is
2.22x10^-15 Kg.
Can we say mass of the ball is increased by 2.22x10^-15 Kg.
In another words, mass of the moving ball is 1+2.22x10^-15Kg, and it will act like a ball of mass 1+2.22x10^-15Kg.
Is this the mass increase we see in special relativity caused by speed?
In such case, it is not a physical increase of mass at all.
A.

oh yes that i was asking all along..!! that i want to point..as if how one could explain such conversion....??
