How to Convert Microwatts to Volt-Amperes
To convert microwatts to volt-amperes, multiply the power by the following conversion ratio: 0.000001 volt-amperes/microwatt.
Since one microwatt is equal to 0.000001 volt-amperes, you can use this simple formula to convert:
The power in volt-amperes is equal to the power in microwatts multiplied by 0.000001.
For example, here's how to convert 5 microwatts to volt-amperes using the formula above.
How Many Volt-Amperes Are in a Microwatt?
There are 0.000001 volt-amperes in a microwatt, which is why we use this value in the formula above.
Our microwatt to volt-ampere calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Microwatts and volt-amperes 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 Volt-Ampere?
A volt-ampere is a unit of power equal to 1 watts (W), the base unit for power. Apparent electrical power unit (equivalent to 1 W at unity power factor). [2]
The volt-ampere is classified as an International System of Units (SI) unit of power. Volt-Amperes can be abbreviated as VA; for example, 1 volt-ampere can be written as 1 VA.
When working with volt-amperes (VA) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, volt-amperes (VA) are widely used across standard power applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting power between microwatts (µW) and volt-amperes (VA), keep full floating-point precision (1 µW = 0.000001 VA; 1 VA = 1,000,000 µW) during intermediate calculations and round only the final volt-ampere figure to match your instrument tolerance.
