Horsepower (hp) to Megawatts (MW) Conversion
Horsepower
Horsepower (hp) is a unit of power originally defined by James Watt in the 1780s to market steam engines against the work output of draft horses. The US mechanical horsepower equals exactly 745.69987158 watts. Multiple definitions exist: mechanical hp (745.7 W), metric hp (735.5 W), and electrical hp (746 W). In the automotive industry, engine power is expressed in horsepower in the US and UK markets, where 1 hp ≈ 0.7457 kW.
Megawatts
The megawatt (MW) is a unit of power equal to exactly 1,000,000 watts (1,000 kW), the standard scale for power plant output and large industrial consumers. A large wind turbine generates 2–15 MW; a typical nuclear reactor unit produces 1,000–1,600 MW (1–1.6 GW); a small hydroelectric dam might produce 10–100 MW. Data centres for large cloud providers can consume 100–500 MW of continuous power.
