About Foot-pound and Kilowatt-hour
The foot-pound is about 1.3558 joules, the work of one pound-force through one foot. US mechanical engineering and firearm muzzle energy use foot-pounds. The kilowatt-hour is exactly 3.6 megajoules. It is the unit on your electricity bill. Household consumption and electric vehicle battery sizes are stated in kilowatt-hours. One Foot-pound equals 3.766161e-7 Kilowatt-hours (1 ft-lb = 3.766161e-7 kWh). Foot-pound is used in US mechanical engineering and in firearm muzzle energy. Kilowatt-hour is used in electricity billing.
Precision and Rounding:Energy factors mix exact definitions (1 kWh = 3,600,000 J; 1 cal = 4.184 J thermochemical) with measured conventions (1 BTU ≈ 1,055.056 J). Nutrition and utility bills round to whole units; engineering heat calculations should keep the full factor until the final step.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
