FAQ
What is the conversion factor from therm to J?
1 therm equals 1.054804e+8 J. To convert, multiply the value in US therms by 1.054804e+8.
How do I convert 1 therm to J?
1 therm = 1.0548e+8 J. For any value, multiply by 1.054804e+8.
How do I convert J back to therm?
Divide by the same factor — or equivalently, multiply by 9.480434e-9. So 1 J = 9.48043e-9 therm.
When would I need to convert US therm to joule?
Energy conversions are needed when reconciling fuel/electrical billing, calculating thermal duties, and aligning calorimetry or HHV/LHV figures across data sources.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
