How to Convert Microwatts to Metric Horsepower
To convert microwatts to metric horsepower, multiply the power by the following conversion ratio: 1.359622e-9 metric horsepower/microwatt.
Since one microwatt is equal to 1.359622e-9 metric horsepower, you can use this simple formula to convert:
The power in metric horsepower is equal to the power in microwatts multiplied by 1.359622e-9.
For example, here's how to convert 5 microwatts to metric horsepower using the formula above.
How Many Metric Horsepower Are in a Microwatt?
There are 1.359622e-9 metric horsepower in a microwatt, which is why we use this value in the formula above.
Our microwatt to horsepower calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Microwatts and metric horsepower are both units used to measure power. Keep reading to learn more about each unit.
What Is a Microwatt?
A microwatt is a unit of power equal to 1/1,000,000 of a watt (0.000001 W). One-millionth of a Watt. [1]
The microwatt is classified as a metric and SI-compatible unit of power. Microwatts can be abbreviated as µW; for example, 1 microwatt can be written as 1 µW.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microwatt (µW) a convenient decimal multiple of the watt (W).
In practice, microwatts (µW) are widely used across fine-tolerance laboratory, analytical, and micro-scale power measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Horsepower?
A horsepower is a unit of power equal to 735.49875 watts (W), the base unit for power. Metric horsepower (75 kgf·m/s = 735.49875 W). [2]
The horsepower is classified as a metric and SI-compatible unit of power. Metric Horsepower can be abbreviated as PS; for example, 1 horsepower can be written as 1 PS.
When working with metric horsepower (PS) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, metric horsepower (PS) are widely used across standard power applications within SI metric workflows, engineering documentation, and technical data sheets.
When converting power between microwatts (µW) and metric horsepower (PS), keep full floating-point precision (1 µW = 1.359622e-9 PS; 1 PS = 735,498,750 µW) during intermediate calculations and round only the final horsepower figure to match your instrument tolerance.
