Convert picojoule/second to horsepower
Please provide values below to convert picojoule/second [pJ/s] to horsepower [hp], or Convert horsepower to picojoule/second.
1 pJ/s = 1.3410e-15 hp. To convert picojoule/second to horsepower, multiply the value by 1.3410e-15; to go the other way, divide by it (1 hp = 7.4570e+14 pJ/s). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 pJ/s = 1.3410e-15 hp
- 1 hp = 7.4570e+14 pJ/s
- 10 pJ/s = 1.3410e-14 hp
- 100 pJ/s = 1.3410e-13 hp
How to Convert Picojoule/second to Horsepower
1 pJ/s = 1.3410218586563e-15 hp
Example: convert 15 pJ/s to hp:
15 pJ/s = 15 × 1.3410218586563e-15 hp = 2.01153278798444e-14 hp

Picojoule/second
A picojoule per second (pJ/s) is a unit of power equivalent to one trillionth of a joule per second, representing an extremely small rate of energy transfer.
History/Origin
The picojoule per second is derived from the SI units of energy (joule) and time (second), with 'pico' denoting a factor of 10^-12. It has been used in scientific contexts requiring precise measurement of very small power levels, especially in fields like nanotechnology and low-power electronics.
Current Use
This unit is used in scientific and engineering applications to quantify extremely low power levels, such as in nanotechnology, bioelectronics, and other fields where minute energy transfer rates are relevant.
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.
