Convert Kilojoules to Terajoules
Convert Kilojoules (kJ) to Terajoules (TJ) instantly and accurately.
Conversion Formula
TJ = kJ × 1.000000000e-9
About Kilojoules
A kilojoule (kJ) is exactly 1,000 J and is the standard energy unit for food and physical chemistry. EU, Australian, and NZ food labels are mandatory in kJ: recommended adult intake is ~8,400 kJ/day. Bond dissociation energies: C-H bond 413 kJ/mol; C=C double bond 614 kJ/mol; N≡N triple bond 945 kJ/mol. Specific heat of water: 4.184 kJ/(kg·K). A cyclist riding at 150 W for one hour expends 540 kJ. Charpy and Izod impact toughness tests record results in J and kJ. 1 kJ = 1,000 J = 239.0 cal = 0.94782 BTU = 0.27778 Wh.
About Terajoules
A terajoule (TJ) is 10¹² J - the scale of nuclear yields in the kiloton range and large industrial accidents. One kiloton of TNT = 4.184 TJ; the Hiroshima bomb (15 kt) released ~62.8 TJ. The Halifax Explosion (1917) released ~3 TJ. A 500 MW coal plant consumes ~51.4 TJ/h of thermal input. Daily primary energy of Denmark is ~250-300 TJ; the UK ~3,800 TJ/day. A 1 GW nuclear reactor at 90% capacity factor generates ~77.7 TJ/day. 1 TJ = 10¹² J = 277,778 kWh = 277.78 MWh = 23.88 ktoe.
