FAQ
What is the conversion factor from MWh to therm?
1 MWh equals 34.12956 therm. To convert, multiply the value in megawatt-hours by 34.12956.
How do I convert 1 MWh to therm?
1 MWh = 34.1296 therm. For any value, multiply by 34.12956.
How do I convert therm back to MWh?
Divide by the same factor — or equivalently, multiply by 0.02930011. So 1 therm = 0.0293001 MWh.
When would I need to convert megawatt-hour 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).
