About Calorie and Foot-pound

The calorie (small calorie) is exactly 4.184 joules — the thermochemical convention, originally the heat to warm one gram of water by 1 °C. Chemistry uses it; food 'Calories' are actually kilocalories. 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 Calorie equals 3.085960033 Foot-pound (1 cal = 3.085960033 ft-lb). Calorie to Foot-pound conversion comes up most often in chemistry heat calculations and in scientific literature, typically when figures need restating for 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).
