About Therm and Kilocalorie

The therm is 100,000 BTU, about 105.5 megajoules. US natural gas utilities bill household consumption in therms. The kilocalorie is 4,184 joules — the food 'Calorie' (capital C) on US nutrition labels. Diet tracking and exercise burn estimates use kilocalories. One Therm equals 25216.44007 Kilocalorie (1 therm = 25216.44007 kcal). Therm to Kilocalorie conversion comes up most often in US natural gas billing and in home heating cost estimates, typically when figures need restating for nutrition labels and diet tracking.

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).
