FAQ

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