About Gigajoule and Therm

The gigajoule is one billion joules, roughly the energy in 26 liters of gasoline. District heating and industrial energy contracts bill in gigajoules. The therm is 100,000 BTU, about 105.5 megajoules. US natural gas utilities bill household consumption in therms. One Gigajoule equals 9.478171203 Therm (1 GJ = 9.478171203 therm). Gigajoule to Therm conversion comes up most often in district heating bills and in industrial energy contracts, 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).
