How to Convert Terawatts to Kilowatts
To convert terawatts to kilowatts, multiply the power by the following conversion ratio: 1,000,000,000 kilowatts/terawatt.
Since one terawatt is equal to 1,000,000,000 kilowatts, you can use this simple formula to convert:
The power in kilowatts is equal to the power in terawatts multiplied by 1,000,000,000.
For example, here's how to convert 5 terawatts to kilowatts using the formula above.
How Many Kilowatts Are in a Terawatt?
There are 1,000,000,000 kilowatts in a terawatt, which is why we use this value in the formula above.
Our terawatt to kilowatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Terawatts and kilowatts are both units used to measure power. Keep reading to learn more about each unit.
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). [1]
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.
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 terawatts (TW) and kilowatts (kW), keep full floating-point precision (1 TW = 1,000,000,000 kW; 1 kW = 1e-9 TW) during intermediate calculations and round only the final kilowatt figure to match your instrument tolerance.
