Use the converter below to change any watts value into megawatts instantly — with formula, conversion table, and real-world examples.

1.0000e-6

Conversion formula

Forward
megawatts = watts × 1.0000e-6
Reverse
watts = megawatts × 1,000,000

Example: 10 W × 1.0000e-6 = 1.0000e-5 MW.

About both units

From

Watt

W

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.

Megawatt

MW

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.

Tips & common mistakes

Quick tips

  • 1 W = 1 J/s = 1 V × 1 A (for DC).
  • LED lighting: 10× more efficient than incandescent.
  • For home appliances, rating × hours used = kWh.

Avoid these

  • Confusing watts (power) with joules (energy).
  • Assuming "100 W bulb" for LED — old incandescent rating.
  • Mixing W with V or A — different quantities.

Frequently asked questions

How many megawatts in a watt?
One watt equals 1.0000e-6 megawatts.
How do I convert watts to megawatts?
Multiply the watt value by 1.0000e-6 to get the equivalent in megawatts.
