FAQ
What is the conversion factor from MWh to kWh?
1 MWh equals 1000 kWh. To convert, multiply the value in megawatt-hours by 1000.
How do I convert 1 MWh to kWh?
1 MWh = 1000 kWh. For any value, multiply by 1000.
How do I convert kWh back to MWh?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 kWh = 0.001 MWh.
When would I need to convert megawatt-hour to kilowatt-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).
