Kilowatt-hour (kWh) and Megawatt (MW) measure different electrical quantities. See how they relate and use context values for a physically meaningful result.
Context values
Some unit families need one extra value for a physically accurate result.
A Megawatt (MW) equals 1e+6 watt(s), a scaled unit of electrical power used for mega-scale electrical work.
No fixed factor — different physical quantities
Kilowatt-hour measures electrical energy and Megawatt measures electrical power. These are different physical quantities, so there is no fixed multiplication factor between them. Use Ohm’s law and energy over time: V = I × R, P = V × I, E = P × time.

Compatibility notice
Kilowatt-hour (kWh) measures electrical energy. Megawatt (MW) measures electrical power. Because these are different physical dimensions, there is no single fixed factor that converts one directly into the other — a numeric answer would be fabricated and misleading.
Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t). Enter voltage, current, resistance, and/or hours in the context fields above the result to get a physically accurate value based on the relationship between kilowatt-hour and megawatt.
Conversion table
A direct numeric table is not shown here because kilowatt hours and megawatts are not directly proportional. Instead, use the calculator above with context values, or convert within a single dimension using the related conversions below.

How kilowatt hours and megawatts relate
Kilowatt-hour and Megawatt belong to different electrical dimensions (electrical energy vs. electrical power), so this page does not fabricate a fixed conversion formula. Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t). Supply the missing context (voltage, current, resistance, or time) in the calculator to compute a real-world equivalent.
Frequently asked questions
Can I convert kilowatt hours directly to megawatts?
