Matter can be converted into energy by annihilation, fission, and fusion.

These are mentioned in

Some examples are

Annihilation occurs when an electron and a positron meet. They annihilate each other and produce two γ ray photons, each with an energy of 511 keV.

e + e+ → γ + γ

Fission is a process in which a nucleus splits into two smaller nuclei. For example,

23592U+10n14156Ba+9236Kr+310n + energy

Fusion is a process in which two nuclei join to form a larger nucleus. For example,

21H+31H42He+10n + energy
