1 foot-pound is closely equal to:
- 1.3558179483314 newton meters A newton metre is dimensionally equal to a joule
A joule is the energy exerted by a force of one newton acting to move an object through a distance of one metre
1 joule is equal to:- 1×107 ergs (exactly) * 6.24150974×1018 eV (electronvolts) * 0.2390 cal (thermochemical gram calories or small calories) * 2.3901×10-4 kcal (thermochemical kilocalories, kilogram calories, large calories or food calories) * 9.4782×10-4 BTU (British thermal unit) * 0.7376 ft·lbf (foot-pound force) * 23.7 ft·pdl (foot-poundals) * 2.7778×10-7 kilowatt-hour * 2.7778×10-4 watt-hour * 9.8692×10-3 liter-atmosphere * 1×10-44 Foe (exactly)
Units defined in terms of the joule include:
- 1 thermochemical calorie = 4.184 J * 1 International Table calorie = 4.1868 J * 1 watt hour = 3600 J * 1 kilowatt hour = 3.6×106 J (or 3.6 MJ) * 1 ton TNT = 4.184 GJ * Hiroshima's "Little Boy" (12-15 kt TNT) = 50-63 TJ
