Convert horsepower to decijoule/second
Please provide values below to convert horsepower [hp] to decijoule/second [dJ/s], or Convert decijoule/second to horsepower.
1 hp = 7457 dJ/s. To convert horsepower to decijoule/second, multiply the value by 7457; to go the other way, divide by it (1 dJ/s = 0.000134102185866 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 = 7457 dJ/s
- 1 dJ/s = 0.000134102185866 hp
- 10 hp = 74570 dJ/s
- 100 hp = 745700 dJ/s
How to Convert Horsepower to Decijoule/second
1 hp = 7457 dJ/s
Example: convert 15 hp to dJ/s:
15 hp = 15 × 7457 dJ/s = 111855 dJ/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.
Decijoule/second
A decijoule per second (dJ/s) is a unit of power equivalent to one-tenth of a joule per second, representing the rate of energy transfer or conversion.
History/Origin
The decijoule is a decimal submultiple of the joule, introduced as part of the metric system to facilitate measurements at smaller scales. Its usage in power calculations, such as decijoules per second, has been consistent with the adoption of SI units, though it is less common in modern practice.
Current Use
Decijoule per second is rarely used in contemporary contexts; power is more commonly expressed in watts (joules per second). When used, it typically appears in specialized scientific or engineering applications requiring fine-grained energy rate measurements at the deci level.
