About Therm and Joule
The therm is 100,000 BTU, about 105.5 megajoules. US natural gas utilities bill household consumption in therms. The joule is the SI derived unit of energy, the work done by a force of one newton over one meter. Physics, chemistry, and food labeling outside the US build on it. One Therm equals 105505585.3 Joules (1 therm = 105505585.3 J). Therm is used in US natural gas billing and in home heating cost estimates. Joule is used in physics and engineering calculations.
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).
