FAQ
What is the conversion factor from J to therm?
1 J equals 9.480434e-9 therm. To convert, multiply the value in joules by 9.480434e-9.
How do I convert 1 J to therm?
1 J = 9.48043e-9 therm. For any value, multiply by 9.480434e-9.
How do I convert therm back to J?
Divide by the same factor — or equivalently, multiply by 1.054804e+8. So 1 therm = 1.0548e+8 J.
When would I need to convert joule to US therm?
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).
