FAQ
What is the conversion factor from MWh to kcal?
1 MWh equals 860420.7 kcal. To convert, multiply the value in megawatt-hours by 860420.7.
How do I convert 1 MWh to kcal?
1 MWh = 860421 kcal. For any value, multiply by 860420.7.
How do I convert kcal back to MWh?
Divide by the same factor — or equivalently, multiply by 1.162222e-6. So 1 kcal = 1.16222e-6 MWh.
When would I need to convert megawatt-hour to kilocalorie?
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).
