Bruce, looks like you also forgot the definition of kinetic
energy (the energy of moving objects). It is equal to the mass
times the velocity squared divided by 2. As a result, your
value above is twice as large as it should be.
Of course, if a given mass is totally converted into energy,
then the energy obtained is the product of the mass time the
velocity of light squared (Einstein's mass-energy formula).
