About Therm and Kilojoule

The therm is 100,000 BTU, about 105.5 megajoules. US natural gas utilities bill household consumption in therms. The kilojoule is 1,000 joules. Food energy in Australia, Europe, and most metric countries is labeled in kilojoules alongside or instead of calories. One Therm equals 105505.5853 Kilojoules (1 therm = 105505.5853 kJ). Therm is used in US natural gas billing and in home heating cost estimates. Kilojoule is used in food labels outside the US.

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).
