About Kilocalorie and Therm

The kilocalorie is 4,184 joules. It is the food 'Calorie' (capital C) on US nutrition labels. Diet tracking and exercise burn estimates use kilocalories. The therm is 100,000 BTU, about 105.5 megajoules. US natural gas utilities bill household consumption in therms. One Kilocalorie equals 0.00003965666831 Therms (1 kcal = 0.00003965666831 therm). Kilocalorie is used in nutrition labels and diet tracking and in exercise calorie burn. Therm is used in US natural gas 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).
