Convert horsepower (550 ft*lbf/s) to picojoule/second

Please provide values below to convert horsepower (550 ft*lbf/s) [hp] to picojoule/second [pJ/s], or Convert picojoule/second to horsepower (550 ft*lbf/s).

1 hp = 7.4570e+14 pJ/s. To convert horsepower (550 ft*lbf/s) to picojoule/second, multiply the value by 7.4570e+14; to go the other way, divide by it (1 pJ/s = 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 pJ/s
  • 1 pJ/s = 1.3410e-15 hp
  • 10 hp = 7.4570e+15 pJ/s
  • 100 hp = 7.4570e+16 pJ/s

Horsepower (550 Ft*lbf/s)

Horsepower (hp) is a unit of power measurement, defined as 550 foot-pounds of work per second (ft·lbf/s).

History/Origin

The horsepower was developed by James Watt in the late 18th century to compare the power of steam engines with draft horses, and it became a standard unit for measuring engine power.

Current Use

Horsepower is still widely used today to rate the power of engines and motors in automotive, aviation, and industrial applications.


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.
