About Kilowatt-hour and Therm
The kilowatt-hour is exactly 3.6 megajoules. It is the unit on your electricity bill. Household consumption and electric vehicle battery sizes are stated in kilowatt-hours. The therm is 100,000 BTU, about 105.5 megajoules. US natural gas utilities bill household consumption in therms. One Kilowatt-hour equals 0.03412141633 Therms (1 kWh = 0.03412141633 therm). Kilowatt-hour is used in electricity billing and in electric vehicle battery capacity. 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).
