Convert horsepower to deciwatt
Please provide values below to convert horsepower [hp] to deciwatt [dW], or Convert deciwatt to horsepower.
1 hp = 7457 dW. To convert horsepower to deciwatt, multiply the value by 7457; to go the other way, divide by it (1 dW = 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 dW
- 1 dW = 0.000134102185866 hp
- 10 hp = 74570 dW
- 100 hp = 745700 dW
How to Convert Horsepower to Deciwatt
1 hp = 7457 dW
Example: convert 15 hp to dW:
15 hp = 15 × 7457 dW = 111855 dW

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.
Deciwatt
A deciwatt (dW) is a unit of power equal to one-tenth of a watt, used to measure small amounts of power.
History/Origin
The deciwatt was introduced as part of the metric system's decimal prefixes to provide convenient submultiples of the watt, though it is rarely used in practice.
Current Use
Deciwatt is rarely used in modern applications; it may appear in specialized scientific contexts or theoretical calculations involving small power levels.
