How to Convert Metric Horsepower to Microwatts
To convert metric horsepower to microwatts, multiply the power by the following conversion ratio: 735,498,750 microwatts/horsepower.
Since one horsepower is equal to 735,498,750 microwatts, you can use this simple formula to convert:
The power in microwatts is equal to the power in metric horsepower multiplied by 735,498,750.
For example, here's how to convert 5 metric horsepower to microwatts using the formula above.
How Many Microwatts Are in a Horsepower?
There are 735,498,750 microwatts in a horsepower, which is why we use this value in the formula above.
Our horsepower to microwatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Metric Horsepower and microwatts are both units used to measure power. Keep reading to learn more about each unit.
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). [1]
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.
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. [2]
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.
When converting power between metric horsepower (PS) and microwatts (µW), keep full floating-point precision (1 PS = 735,498,750 µW; 1 µW = 1.359622e-9 PS) during intermediate calculations and round only the final microwatt figure to match your instrument tolerance.
