Conversion Formula
aJ = t(TNT) × 4.184000000e+27
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 Attojoules
An attojoule (aJ) is 10⁻¹⁸ J - the scale of individual X-ray photons and superconducting qubit circuits. A 1 keV X-ray photon carries 160 aJ; a visible green photon (~550 nm) carries ~0.36 aJ. Josephson junction energies in superconducting qubits are set in tens to hundreds of aJ to achieve quantum coherence at millikelvin temperatures. XRISM's cryogenic TES X-ray spectrometer resolves individual photon energies at the hundreds-of-aJ level with ~7 eV FWHM resolution. 1 aJ = 10⁻¹⁸ J = 6.242 eV.
