Conversion formula

Forward

watts = megawatts × 1,000,000

Reverse

megawatts = watts × 1.0000e-6

Example: 10 MW × 1,000,000 = 10,000,000 W.

About both units

From

Megawatt

The megawatt equals 1,000,000 watts. Used for power-station capacity and large industrial loads. Typical wind turbine: 2–15 MW. Nuclear reactor: 1000 MW (electrical). A city of 100,000 needs roughly 100 MW peak.

Real-world: Large wind turbine: 5–15 MW. Nuclear reactor: 1000 MW. London's peak demand: ~6000 MW.

Watt

The watt is the SI unit of power — 1 joule per second. Named after James Watt. Common examples: LED bulb 5–10 W, laptop 45–100 W, kettle 2000–3000 W, car engine 50,000+ W.

Real-world: LED bulb: 5–10 W. Laptop: 45 W. Kettle: 2200 W. Oven: 2000 W. Sun per m² on Earth: 1361 W/m².

Tips & common mistakes

Quick tips

1 MW = 1000 kW = 1,000,000 W.
GW (gigawatt) = 1000 MW for country-scale generation.
For energy output, multiply MW × hours = MWh.

Avoid these

Confusing MW (power) with MWh (energy).
Using kW for large generation — numbers become unwieldy.
Mixing installed capacity (MW) with actual output (which depends on use).

Frequently asked questions

How many watts in a megawatt?
