FAQ
What is the conversion factor from MWh to BTU?
1 MWh equals 3412142 BTU. To convert, multiply the value in megawatt-hours by 3412142.
How do I convert 1 MWh to BTU?
1 MWh = 3.41214e+6 BTU. For any value, multiply by 3412142.
How do I convert BTU back to MWh?
Divide by the same factor — or equivalently, multiply by 2.930711e-7. So 1 BTU = 2.93071e-7 MWh.
When would I need to convert megawatt-hour to International Table BTU?
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).
