Convert Tons of TNT to Nanojoules
Convert Tons of TNT (t(TNT)) to Nanojoules (nJ) instantly and accurately.
Conversion Formula
nJ = t(TNT) × 4.184000000e+18
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 Nanojoules
A nanojoule (nJ) is 10⁻⁹ J - the scale of ultrashort laser pulses, flash memory write operations, and cellular ATP reserves. A Ti:sapphire laser oscillator produces pulses of 1-20 nJ at 80 MHz. Flash NAND programming costs ~1-10 nJ/bit written; a read is ~0.1 nJ/bit. The total ATP energy stored in a single red blood cell is ~1-5 nJ. The kinetic energy of a 1 µg particle at 1.4 m/s is ~1 nJ, illustrating that nanojoules describe real nanoscale mechanical events. 1 nJ = 10⁻⁹ J.
