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

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.
Femtojoule/second
A femtojoule per second (fJ/s) is a unit of power representing the rate of energy transfer of one femtojoule (10^-15 joules) per second.
History/Origin
The femtojoule/second unit emerged with the development of high-precision measurements in nanotechnology and quantum physics, where extremely small energy transfer rates are relevant. It is derived from the SI units of energy (joule) and time (second), with 'femto' denoting 10^-15.
Current Use
The femtojoule/second is used in scientific research to quantify very small power levels, particularly in fields like nanotechnology, quantum computing, and molecular physics, where energy transfer rates are extremely low.
