What does milliwatt measure?

Milliwatt (mW) measures power as one thousandth of a watt, indicating the rate of energy transfer often used in small electronic devices.

What is horsepower used for?

Horsepower (hp) is a traditional unit expressing power for engines, motors, and mechanical equipment, commonly used in automotive and industrial contexts.

Why are converted horsepower values so small when converting from milliwatts?

Because horsepower is a much larger unit than milliwatt, values converted from milliwatts result in very small numbers.

What Is This Tool?

This converter transforms power measurements from milliwatt (mW), a small SI unit commonly used in electronics, into horsepower (hp, hp (UK)), a larger non-SI unit traditionally used for engines and mechanical devices.

How to Use This Tool?

Enter the power value in milliwatt (mW) that you want to convert.
Select horsepower (hp, hp (UK)) as the target unit.
Click the convert button to get the equivalent power in horsepower.
Use the result to compare power ratings across different domains.

Key Features

Converts milliwatt to mechanical/imperial horsepower values.
Includes precise conversion rate based on established definitions.
Facilitates comparison of small-scale electrical power with larger mechanical power units.
User-friendly and accessible directly in your browser.

Examples

Converting 500 mW results in approximately 0.000670511 hp.
Converting 1000 mW (1 watt) equals about 0.001341022 hp.

Common Use Cases

Evaluating power consumption of small electronic circuits or sensors.
Comparing output power of audio amplifiers and portable devices to engine power ratings.
Expressing optical and RF device outputs in terms of horsepower for engineering reports.
Referencing engine or motor power in automotive and mechanical engineering.

Tips & Best Practices

Ensure the correct hp variant is selected; this tool uses mechanical/imperial horsepower definitions.
Recognize that converted horsepower values from milliwatts will be very small due to unit size differences.
Use the converter to complement engineering specifications that span both electronic and mechanical domains.
Confirm unit standards are clearly stated to avoid confusion between SI and non-SI units.

Limitations

Horsepower is significantly larger than milliwatt, so output values are very small and may not be practical for precise measurements at low power.
Different horsepower variants exist and selecting the incorrect one can cause inaccuracies.
Millwatt is an SI unit, while horsepower is non-SI and used conventionally, which can lead to misunderstanding without clear context.
