How to Convert Volt-Amperes to Terawatts
To convert volt-amperes to terawatts, multiply the power by the following conversion ratio: 1e-12 terawatts/volt-ampere.
Since one volt-ampere is equal to 1e-12 terawatts, you can use this simple formula to convert:
The power in terawatts is equal to the power in volt-amperes multiplied by 1e-12.
For example, here's how to convert 5 volt-amperes to terawatts using the formula above.
How Many Terawatts Are in a Volt-Ampere?
There are 1e-12 terawatts in a volt-ampere, which is why we use this value in the formula above.
Our volt-ampere to terawatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Volt-Amperes and terawatts 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 Terawatt?
A terawatt is a unit of power equal to 1e+12 watts (W), the base unit for power. Equal to 10¹² Watts (1,000 GW). [2]
The terawatt is classified as an International System of Units (SI) unit of power. Terawatts can be abbreviated as TW; for example, 1 terawatt can be written as 1 TW.
In the metric system, "tera" is the standard SI prefix for trillions, or 10¹². This makes the terawatt (TW) a convenient decimal multiple of the watt (W).
In practice, terawatts (TW) are widely used across large-scale industrial, bulk, and macro-level power specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting power between volt-amperes (VA) and terawatts (TW), keep full floating-point precision (1 VA = 1e-12 TW; 1 TW = 1e+12 VA) during intermediate calculations and round only the final terawatt figure to match your instrument tolerance.
