Convert horsepower (550 ft*lbf/s) to decijoule/second
Please provide values below to convert horsepower (550 ft*lbf/s) [hp] to decijoule/second [dJ/s], or Convert decijoule/second to horsepower (550 ft*lbf/s).
1 hp = 7457 dJ/s. To convert horsepower (550 ft*lbf/s) 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

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.
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.
