Convert horsepower to hectojoule/second
Please provide values below to convert horsepower [hp] to hectojoule/second [hJ/s], or Convert hectojoule/second to horsepower.
1 hp = 7.457 hJ/s. To convert horsepower to hectojoule/second, multiply the value by 7.457; to go the other way, divide by it (1 hJ/s = 0.134102185866 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 = 7.457 hJ/s
- 1 hJ/s = 0.134102185866 hp
- 10 hp = 74.57 hJ/s
- 100 hp = 745.7 hJ/s
How to Convert Horsepower to Hectojoule/second
1 hp = 7.457 hJ/s
Example: convert 15 hp to hJ/s:
15 hp = 15 × 7.457 hJ/s = 111.855 hJ/s

Horsepower
Horsepower (hp) is a unit of power measurement originally developed to compare the power of engines and motors, representing the rate at which work is done or energy is transferred.
History/Origin
The term was introduced in the late 18th century by James Watt to compare the power of steam engines to draft horses. It became a standard unit in engineering and automotive industries, with its definition evolving over time from mechanical to metric standards.
Current Use
Horsepower is widely used today to rate the power output of engines, motors, and other machinery, especially in automotive, aerospace, and industrial applications. It remains a common unit for expressing engine power in many countries.
Hectojoule/second
Hectojoule per second (hJ/s) is a unit of power representing one hundred joules of energy transferred or converted per second.
History/Origin
The unit hJ/s is derived from the SI unit joule (J) and the metric prefix hecto- (h), used to express larger quantities of energy transfer rate, particularly in scientific and engineering contexts. It has been used as an alternative to watts in certain fields, though watts are more standard.
Current Use
Hectojoule per second is occasionally used in scientific and engineering applications to quantify power, especially in contexts where larger energy transfer rates are involved. However, the watt (W) remains the standard SI unit for power, and hJ/s is less common in everyday use.
