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

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

1 hp = 7.457e-07 GJ/s. To convert horsepower (550 ft*lbf/s) to gigajoule/second, multiply the value by 7.457e-07; to go the other way, divide by it (1 GJ/s = 1341021.85866 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 = 7.457e-07 GJ/s
  • 1 GJ/s = 1341021.85866 hp
  • 10 hp = 7.457e-06 GJ/s
  • 100 hp = 7.457e-05 GJ/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.


Gigajoule/second

A gigajoule per second (GJ/s) is a unit of power equivalent to one gigajoule of energy transferred or converted per second.

History/Origin

The gigajoule per second emerged as a larger-scale unit of power measurement, primarily used in scientific and engineering contexts to quantify high power levels, especially in energy production and consumption. It is derived from the SI unit joule and the prefix giga, combined with the second as the time unit.

Current Use

GJ/s is used in fields such as energy industry, power generation, and large-scale energy transfer analysis to express high power rates, often in the context of power plants, energy infrastructure, and large energy projects.
