Horsepower (hp) to Gigawatts (GW) 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.
Gigawatts
The gigawatt (GW) is a unit of power equal to exactly 1,000,000,000 watts (10⁹ W), the scale of national electrical grids and large-scale power generation. The total installed electricity generation capacity of France is approximately 130 GW; that of the United States exceeds 1,100 GW. A lightning bolt peaks at around 1 TW for microseconds. The rapid growth of solar and wind power is often described in gigawatts of installed capacity added per year.
