How to Convert Volt-Amperes to Kilowatts
To convert volt-amperes to kilowatts, multiply the power by the following conversion ratio: 0.001 kilowatts/volt-ampere.
Since one volt-ampere is equal to 0.001 kilowatts, you can use this simple formula to convert:
The power in kilowatts is equal to the power in volt-amperes multiplied by 0.001.
For example, here's how to convert 5 volt-amperes to kilowatts using the formula above.
How Many Kilowatts Are in a Volt-Ampere?
There are 0.001 kilowatts in a volt-ampere, which is why we use this value in the formula above.
Our volt-ampere to kilowatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Volt-Amperes and kilowatts are both units used to measure power. Keep reading to learn more about each unit.
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). [1]
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.
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). [2]
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.
When converting power between volt-amperes (VA) and kilowatts (kW), keep full floating-point precision (1 VA = 0.001 kW; 1 kW = 1,000 VA) during intermediate calculations and round only the final kilowatt figure to match your instrument tolerance.
