Convert horsepower (water) to kilojoule/second
Please provide values below to convert horsepower (water) [hp (water)] to kilojoule/second [kJ/s], or Convert kilojoule/second to horsepower (water).
1 hp (water) = 0.746043 kJ/s. To convert horsepower (water) to kilojoule/second, multiply the value by 0.746043; to go the other way, divide by it (1 kJ/s = 1.34040531176 hp (water)). 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 (water) = 0.746043 kJ/s

Horsepower (Water)
Horsepower (water) is a unit of power used to measure the rate of water flow or energy transfer, based on the power exerted by a water stream.
History/Origin
The water horsepower originated in the 19th century as a way to quantify the power of water wheels and turbines, with its value historically linked to the energy produced by a specific flow of water under certain conditions.
Current Use
Today, water horsepower is primarily used in hydraulic engineering and water power industries to specify the capacity of water turbines, pumps, and other hydraulic equipment.
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.
