About Megajoule and Therm
The megajoule is one million joules. Fuel energy density, gas billing in some countries, and crash test energies are quoted in megajoules. The therm is 100,000 BTU, about 105.5 megajoules. US natural gas utilities bill household consumption in therms. One Megajoule equals 0.009478171203 Therm (1 MJ = 0.009478171203 therm). Megajoule to Therm conversion comes up most often in fuel energy density figures and in natural gas billing, typically when figures need restating for 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).
