Energy produced per gram of fusion fuel

Electronvolts per atomic mass unit = Generated electronvolts / (Fuel 1 + Fuel 2);
// From 1 [kg] = 1.6605402 * 10^27 [u]
Atomic mass per gram = 10^24 / 1.6605402;
electronvolts per gram = electronvolts per atomic mass * atomic mass per gram;
// From 1 [J] = 1.60217733 / 10^19 [eV], convert to MeV
Joules per electronvolt = 1.60217733 / 10^(19-6);
// Answer
Joules per gram = electron volts per gram * joules per electron volt;
Gigajoules per gram = joules per gram / 10^9;
