Convert horsepower (electric) to kilojoule/second
Please provide values below to convert horsepower (electric) [hp (electric)] to kilojoule/second [kJ/s], or Convert kilojoule/second to horsepower (electric).
1 hp (electric) = 0.746 kJ/s. To convert horsepower (electric) to kilojoule/second, multiply the value by 0.746; to go the other way, divide by it (1 kJ/s = 1.34048257373 hp (electric)). 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 (electric) = 0.746 kJ/s
- 1 kJ/s = 1.34048257373 hp (electric)
- 10 hp (electric) = 7.46 kJ/s
- 100 hp (electric) = 74.6 kJ/s
How to Convert Horsepower (Electric) to Kilojoule/second
1 hp (electric) = 0.746 kJ/s
Example: convert 15 hp (electric) to kJ/s:
15 hp (electric) = 15 × 0.746 kJ/s = 11.19 kJ/s

Horsepower (Electric)
Electric horsepower (hp) is a unit of power used to measure the rate at which electrical energy is converted into mechanical energy or work, equivalent to approximately 746 watts.
History/Origin
The electric horsepower was developed as an adaptation of the mechanical horsepower to quantify electrical power output, especially in electric motors and generators. It became a standard unit in electrical engineering to express the power of electric motors and appliances.
Current Use
Electric horsepower is used primarily in specifying the power of electric motors, generators, and other electrical devices, particularly in industries where electrical power measurement is essential for performance and efficiency assessments.
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.
