If one would try to correct the vagueness of "mass is converted into
energy" by saying, "the mass of 'γ + γ' is smaller than the mass
of 'e⁺ + e⁻'" (thereby saying "of what"), then this would be wrong.

  And, not to be vague, one also needs to explain what "+" means here.

  In QT, it would be the tensor product, and, in QFT, the application
  of two creation operators with the corresponding momenta and spins to
  the vacuum state. I.e., "e⁺ + e⁻" is the compound system, the mass of
  which differs from the sum of the two components taken in isolation.
