How to Convert Kilowatts to Microwatts
To convert kilowatts to microwatts, multiply the power by the following conversion ratio: 1,000,000,000 microwatts/kilowatt.
Since one kilowatt is equal to 1,000,000,000 microwatts, you can use this simple formula to convert:
The power in microwatts is equal to the power in kilowatts multiplied by 1,000,000,000.
For example, here's how to convert 5 kilowatts to microwatts using the formula above.
How Many Microwatts Are in a Kilowatt?
There are 1,000,000,000 microwatts in a kilowatt, which is why we use this value in the formula above.
Our kilowatt to microwatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilowatts and microwatts are both units used to measure power. Keep reading to learn more about each unit.
What Is a Kilowatt?
A kilowatt is a unit of power equal to 1,000 watts (W), the base unit for power. Equal to 1,000 Watts (1 kJ/s). [1]
The kilowatt is classified as a metric and SI-compatible unit of power. Kilowatts can be abbreviated as kW; for example, 1 kilowatt can be written as 1 kW.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilowatt (kW) a convenient decimal multiple of the watt (W).
In practice, kilowatts (kW) are widely used across large-scale industrial, bulk, and macro-level power specifications 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 kilowatts (kW) and microwatts (µW), keep full floating-point precision (1 kW = 1,000,000,000 µW; 1 µW = 1e-9 kW) during intermediate calculations and round only the final microwatt figure to match your instrument tolerance.
