1 Megawatt = 1000000 Watt
Key Formulas
Kilowatt → Horsepower (mech)
hp = kW × 1.34102Horsepower (mech) → Kilowatt
kW = hp × 0.7457Watt → Kilowatt
kW = W × 0.001Kilowatt → Watt
W = kW × 1000Formula
W = MW × 1,000,000Power plants, solar farms, and wind projects are rated in megawatts, while individual loads — motors, heaters, computers — are rated in watts. Converting MW to watts is essential when calculating how many homes a plant can power, or when expressing a large facility's electrical supply in terms an appliance-level engineer can work with. A 3 MW wind turbine supplies 3,000,000 W = enough for about 2,000 homes at 1,500 W average each.

Real-World Examples
A 1 MW small wind turbine = 1,000,000 W — enough to continuously supply about 600–800 average homes.
1 MW = 1000000 W
A 0.5 MW utility battery storage system = 500,000 W — capable of powering 300 homes during a grid outage.
0.5 MW = 500000 W
A 10 MW gas peaker plant = 10,000,000 W — called into service during demand spikes to prevent blackouts.
10 MW = 10000000 W
A 0.1 MW rooftop solar array on a warehouse = 100,000 W — covering about a quarter of the building's daytime load.
0.1 MW = 100000 W
