About Watt-hour and Foot-pound
The watt-hour is exactly 3,600 joules: one watt sustained for one hour. Battery capacities for phones, laptops, and e-bikes are rated in watt-hours. 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. One Watt-hour equals 2655.223737 Foot-pounds (1 Wh = 2655.223737 ft-lb). Watt-hour is used in battery capacity ratings and in small device power consumption. Foot-pound is used in US mechanical engineering.
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).
