Convert horsepower to femtowatt
Please provide values below to convert horsepower [hp] to femtowatt [fW], or Convert femtowatt to horsepower.
1 hp = 7.4570e+17 fW. To convert horsepower to femtowatt, multiply the value by 7.4570e+17; to go the other way, divide by it (1 fW = 1.3410e-18 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+17 fW
- 1 fW = 1.3410e-18 hp
- 10 hp = 7.4570e+18 fW
- 100 hp = 7.4570e+19 fW
How to Convert Horsepower to Femtowatt
1 hp = 7.457e+17 fW
Example: convert 15 hp to fW:
15 hp = 15 × 7.457e+17 fW = 1.11855e+19 fW

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.
Femtowatt
A femtowatt (fW) is a unit of power equal to 10^-15 watts, representing an extremely small amount of power.
History/Origin
The femtowatt was introduced as part of the SI prefixes to measure very small quantities of power, particularly in scientific and technological contexts, gaining recognition as the need to quantify minute power levels grew.
Current Use
Femtowatts are used in fields such as quantum physics, nanotechnology, and optical measurements, where precise measurement of extremely low power levels is required.
