Convert kilowatt-hours (kWh) to megawatt-hours (MWh).
Factor1 kWh = 0.001 MWh
Converter
kWh
Accepts numbers or expressions, e.g. 150 + 14.7
Result
MWh
Rendered to 6 significant figures.
Formula
Formula
MWh = kWh × 0.001
Multiply any value in kilowatt-hours by 0.001 to obtain the value in megawatt-hours.
Worked example
Convert 1000 kWh to MWh.
- 01Start with 1000 kWh.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 MWh.
Result1000 kWh = 1 MWh

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