E = (1 kg) × (299,792,458 m/s)2 = 89,875,517,873,681,764 J (≈90 × 1015 Joules)
Accordingly, one gram of mass — the mass of a U.S. dollar bill — is equivalent to the following amounts of energy:
≡ 89,875,517,873,681.764 J (≈90 terajoules), precisely by definition
≡ 24,965,421.631 578 267 777… kilowatt-hours (≈25 GW-hours)
= 21,466,398,651,400.058 278 398 777 1090 calories (≈21 Tcal) [1]
= 21.466 398 651 400 058 278 398 777 1090 kilotons of TNT-equivalent energy (≈21 kt) [1]
= 85,185,554,537.701 118 960 880 666 4808 BTUs (≈85 billion BTUs) [1]
Therefore, 1+1 must be equal to 2.
