Convert horsepower to picowatt
Please provide values below to convert horsepower [hp] to picowatt [pW], or Convert picowatt to horsepower.
1 hp = 7.4570e+14 pW. To convert horsepower to picowatt, multiply the value by 7.4570e+14; to go the other way, divide by it (1 pW = 1.3410e-15 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 = 7.4570e+14 pW
- 1 pW = 1.3410e-15 hp
- 10 hp = 7.4570e+15 pW
- 100 hp = 7.4570e+16 pW
How to Convert Horsepower to Picowatt
1 hp = 745700000000000 pW
Example: convert 15 hp to pW:
15 hp = 15 × 745700000000000 pW = 1.11855e+16 pW

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.
Picowatt
A picowatt (pW) is a unit of power equal to one trillionth (10^-12) of a watt.
History/Origin
The picowatt was introduced as part of the SI prefixes to measure extremely small amounts of power, especially in scientific and technological contexts, following the standardization of the watt as the SI unit of power.
Current Use
Picowatts are used in fields such as electronics, physics, and biology to quantify very low power levels, including in sensor measurements, quantum physics, and nanotechnology applications.
