What does one milliwatt represent?

A milliwatt is one thousandth of a watt and measures power equal to one joule per second, often used for low power electronic devices.

Where is metric horsepower typically used?

Metric horsepower is used to measure mechanical power, especially in automotive engines and industrial motors primarily in Europe and Asia.

Can I use this converter for high power electrical devices?

This tool is best for low power measurements; converting high power values is less practical due to scale differences.

Click the convert button to see the equivalent power in metric horsepower.
Review the conversion result and use it for your application.

Key Features

Converts milliwatt values to metric horsepower instantly.
Supports power measurements relevant to electronics and automotive sectors.
Browser-based and simple to use without installation.
Includes practical examples to illustrate conversion steps.

Examples

Convert 500 mW to horsepower (metric): 500 × 0.0000013596216173039 = 0.00067981 horsepower.
Convert 1000 mW to horsepower (metric): 1000 × 0.0000013596216173039 = 0.00135962 horsepower.

Common Use Cases

Measuring power consumption or output of small electronic components like LEDs and sensors.
Expressing engine power ratings for vehicles in European and Asian markets.
Specifying output power for industrial motors, pumps, and generators in datasheets.

Tips & Best Practices

Always check that you are converting within the correct power domains for meaningful comparisons.
Use the tool for small power levels typical of electronic devices when translating to mechanical power.
Confirm unit selections before converting to ensure accuracy.
Be aware of the scale difference to understand the small resulting horsepower values from milliwatt inputs.

Limitations

Conversion involves very small values, which may reduce precision due to rounding.
Not practical for converting large power values due to the huge scale difference.
Should not be used to compare electrical and mechanical power values without the proper context.
