FAQ
What is the conversion factor from therm to MJ?
1 therm equals 105.4804 MJ. To convert, multiply the value in US therms by 105.4804.
How do I convert 1 therm to MJ?
1 therm = 105.48 MJ. For any value, multiply by 105.4804.
How do I convert MJ back to therm?
Divide by the same factor — or equivalently, multiply by 0.009480434. So 1 MJ = 0.00948043 therm.
When would I need to convert US therm to megajoule?
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).
