How to Convert Microwatts to Megawatts
To convert microwatts to megawatts, multiply the power by the following conversion ratio: 1e-12 megawatts/microwatt.
Since one microwatt is equal to 1e-12 megawatts, you can use this simple formula to convert:
The power in megawatts is equal to the power in microwatts multiplied by 1e-12.
For example, here's how to convert 5 microwatts to megawatts using the formula above.
How Many Megawatts Are in a Microwatt?
There are 1e-12 megawatts in a microwatt, which is why we use this value in the formula above.
Our microwatt to megawatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Microwatts and megawatts 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 Megawatt?
A megawatt is a unit of power equal to 1,000,000 watts (W), the base unit for power. Equal to 1,000,000 Watts (1,000 kW). [2]
The megawatt is classified as a metric and SI-compatible unit of power. Megawatts can be abbreviated as MW; for example, 1 megawatt can be written as 1 MW.
In the metric system, "mega" is the standard SI prefix for millions, or 10⁶. This makes the megawatt (MW) a convenient decimal multiple of the watt (W).
In practice, megawatts (MW) are widely used across large-scale industrial, bulk, and macro-level power specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting power between microwatts (µW) and megawatts (MW), keep full floating-point precision (1 µW = 1e-12 MW; 1 MW = 1e+12 µW) during intermediate calculations and round only the final megawatt figure to match your instrument tolerance.
