Energy in One Gram of Mass
This is determined by equation E = m c2, where c = speed of light = 3 x 108 meters/sec. Note units, in the SI system energy is in Joules, mass in kg, distances in meters
E = m · c2
E = (0,001 kg) · (3 · 108 m/s)2
E = 9 · 1013 J
E = (0,001 kg) · (3 · 108 m/s)2
E = 25 000 MWh
c = 299 792 458 meters per second if the exact value
To put it into perspective, it's roughly equivalent to the energy released by about 21.5 kilotons of TNT.
