How many watts are in a megawatt?

One megawatt equals exactly 1,000,000 watts (one million watts). To convert megawatts to watts, multiply by 1,000,000. For example, 2.5 MW = 2,500,000 W.

What is the difference between MW and kW?

A megawatt (MW) equals 1,000 kilowatts (kW) or 1,000,000 watts (W). Kilowatts are used for household and commercial equipment; megawatts are used for power plants and grid-scale systems.

How large is a megawatt in practical terms?

One megawatt can power roughly 400–900 average US homes, depending on location and season. A typical utility-scale wind turbine produces 2–3 MW at rated wind speed. A large coal plant may produce 500–1,000 MW.

Is this conversion the same for AC and DC power?

Yes — the MW-to-W ratio (× 1,000,000) applies to both AC and DC systems. AC systems also involve power factor corrections, but those are separate from this basic unit conversion.

How do megawatts relate to megawatt-hours?

Megawatts (MW) measure power — the instantaneous rate of energy delivery. Megawatt-hours (MWh) measure energy — the total amount delivered over time. Energy (MWh) = Power (MW) × Time (hours). A 100 MW plant running for 10 hours produces 1,000 MWh.
