Convert Tons of TNT to Exajoules
Convert Tons of TNT (t(TNT)) to Exajoules (EJ) instantly and accurately.
Conversion Formula
EJ = t(TNT) × 4.184000000e-9
About Tons of TNT
A ton of TNT is an energy unit defined as exactly 10⁹ thermochemical calories = 4.184 GJ. The Trinity test (first nuclear weapon, 1945) yielded ~21 kilotons TNT = 87.9 TJ. The Tsar Bomba yielded ~50 megatons TNT = 209 PJ - the largest human-made explosion in history. Hiroshima's Little Boy yielded ~15 kilotons = 62.8 TJ. The Tunguska 1908 airburst released ~10-15 megatons TNT. Earthquake magnitude 6.0 releases ~63 kilotons TNT equivalent in seismic energy. 1 t(TNT) = 4.184 GJ = 4,184 MJ = 1,162.8 kWh.
About Exajoules
An exajoule (EJ) is 10¹⁸ J - the scale of global energy consumption. World primary energy supply in 2022 was ~580-610 EJ: coal ~160 EJ; oil ~190 EJ; gas ~145 EJ; nuclear ~26 EJ; wind ~8 EJ; solar PV ~8 EJ. Global electricity generation of ~29,000 TWh = 104 EJ. Solar energy incident on Earth's atmosphere is ~5.5 × 10⁶ EJ/year - approximately 9,000× total human demand. Annual fossil fuel combustion releases ~490 EJ/year, producing ~36.8 Gt CO₂. 1 EJ = 10¹⁸ J = 277.78 TWh = 238.85 Mtoe.
