Convertisseur de Chevaux-vapeur en Mégawatts

Horsepower (hp) is an imperial unit of power equal to approximately 745.7 watts, originally defined by James Watt to compare steam engine output to draft horses. It remains the standard unit for rating car engines, lawnmowers, and boat motors, especially in the United States. One horsepower equals about 0.7457 kilowatts or 1.0139 metric horsepower.

The megawatt (MW) equals one million watts, used to express the output of power plants, large industrial facilities, and data centers. A typical wind turbine generates 2–3 MW, while a large coal plant may produce 500–1,000 MW. One megawatt can power roughly 800–1,000 homes simultaneously.
