What does horsepower [hp, hp (UK)] measure?

Horsepower [hp, hp (UK)] is a mechanical power unit defined as 550 foot-pounds per second, approximately equal to 745.7 watts, used to express the rate of doing work.

When should I use centiwatt [cW] units?

Centiwatt is suitable for quantifying very low power, such as in ultra-low-power electronics, small indicator LEDs, or tiny energy harvesters.

Can I convert any horsepower variant using this tool?

The tool is primarily aimed at the common mechanical/imperial horsepower [hp, hp (UK)]; conversions depend on the specific variant used.

How to Use This Tool?

Enter the value in horsepower you want to convert.
Select the input unit as horsepower [hp, hp (UK)].
Choose centiwatt [cW] as the output unit.
Click the convert button to see the equivalent power in centiwatt.

Key Features

Converts horsepower (hp, hp (UK)) to centiwatt (cW) accurately based on standard definitions.
Supports conversion between a large mechanical power unit and a very small electronic power unit.
Easy to use online interface suitable for automotive, electrical engineering, and sensor applications.

Examples

2 horsepower equals 149139.974316458 centiwatt.
0.5 horsepower equals 37284.9935791145 centiwatt.

Common Use Cases

Converting engine power ratings in automotive and motorcycle specifications to low-power electronic measurements.
Translating power data for electric motors, pumps, or small machinery into sensor-level power units.
Comparing high-power mechanical outputs to the power consumed or generated by ultra-low-power electronics or energy harvesters.

Tips & Best Practices

Ensure you know which horsepower variant applies to your context for accurate conversions.
Use the converter to understand power across different scales from industrial machinery to tiny electronics.
Verify unit selections carefully to avoid confusion between horsepower and centiwatt units.

Limitations

Several horsepower variants exist, so the exact conversion depends on the specific type used.
Centiwatt units are best for very low power levels and may not be ideal for extremely large or highly variable outputs requiring finer precision.
