Do we have real time example of reverse of E=mc^2.ie:m=E/c^2?

Yes, of course. There are many electron-positron machines as an example that annihilate to form pure energy (generally photons). Which will usually soon oscillate into particles that decay at those energies.

Yes we do, it is this;

Reply:This is most easily seen in subatomic physics. Radioactive isotopes decay at a known rate and generate energy in the form of matter and energy. The energy is in the form of heat and can be measured exactly. The matter can be either photons, electrons or even atomic nuclei. In the case of subatomic particles like neutrons, the mass can be calculated knowing the rate of radioactive decay. This gives the number of particles lost per second. The overall equation is then :





Original mass = mass of evolved particle + energy





The difference in the masses of the particles can then be shown to be equal to the heat energy divided by the square of the speed of light:





(M1 - M2) = E/C^2





This was most likley how Einstein proved his theory.
