Convert horsepower to gigawatt
Please provide values below to convert horsepower [hp] to gigawatt [GW], or Convert gigawatt to horsepower.
1 hp = 7.457e-07 GW. To convert horsepower to gigawatt, multiply the value by 7.457e-07; to go the other way, divide by it (1 GW = 1341021.85866 hp). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hp = 7.457e-07 GW
- 1 GW = 1341021.85866 hp
- 10 hp = 7.457e-06 GW
- 100 hp = 7.457e-05 GW
How to Convert Horsepower to Gigawatt
1 hp = 7.457e-07 GW
Example: convert 15 hp to GW:
15 hp = 15 × 7.457e-07 GW = 1.11855e-05 GW

Horsepower
Horsepower (hp) is a unit of power measurement originally developed to compare the power of engines and motors, representing the rate at which work is done or energy is transferred.
History/Origin
The term was introduced in the late 18th century by James Watt to compare the power of steam engines to draft horses. It became a standard unit in engineering and automotive industries, with its definition evolving over time from mechanical to metric standards.
Current Use
Horsepower is widely used today to rate the power output of engines, motors, and other machinery, especially in automotive, aerospace, and industrial applications. It remains a common unit for expressing engine power in many countries.
Gigawatt
A gigawatt (GW) is a unit of power equal to one billion watts, used to measure large-scale electrical power generation or consumption.
History/Origin
The gigawatt was introduced as part of the metric system's adoption for expressing large power quantities, particularly in the context of electrical engineering and energy projects, becoming widely used in the 20th century with the growth of large power plants and national grids.
Current Use
Gigawatts are commonly used today to quantify the capacity of power plants, energy production, and national or regional power consumption levels, especially in the context of renewable energy projects and large-scale infrastructure.
