Convert horsepower (550 ft*lbf/s) to kilojoule/second
Please provide values below to convert horsepower (550 ft*lbf/s) [hp] to kilojoule/second [kJ/s], or Convert kilojoule/second to horsepower (550 ft*lbf/s).
1 hp = 0.7457 kJ/s. To convert horsepower (550 ft*lbf/s) to kilojoule/second, multiply the value by 0.7457; to go the other way, divide by it (1 kJ/s = 1.34102185866 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 = 0.7457 kJ/s
- 1 kJ/s = 1.34102185866 hp
- 10 hp = 7.457 kJ/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.
Kilojoule/second
A kilojoule per second (kJ/s) is a unit of power equivalent to one kilojoule of energy transferred or converted per second.
History/Origin
The kilojoule per second is derived from the SI units of energy (joule) and time (second), and has been used in scientific and engineering contexts to measure power, especially in fields like physics and energy studies.
Current Use
It is used to quantify power in various applications, including electrical power, mechanical power, and energy transfer rates, particularly where kilojoules and seconds are the relevant units.
