How to Convert Kilowatts to Gigawatts
To convert kilowatts to gigawatts, multiply the power by the following conversion ratio: 0.000001 gigawatts/kilowatt.
Since one kilowatt is equal to 0.000001 gigawatts, you can use this simple formula to convert:
The power in gigawatts is equal to the power in kilowatts multiplied by 0.000001.
For example, here's how to convert 5 kilowatts to gigawatts using the formula above.
How Many Gigawatts Are in a Kilowatt?
There are 0.000001 gigawatts in a kilowatt, which is why we use this value in the formula above.
Our kilowatt to gigawatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilowatts and gigawatts are both units used to measure power. Keep reading to learn more about each unit.
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). [1]
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.
What Is a Gigawatt?
A gigawatt is a unit of power equal to 1,000,000,000 watts (W), the base unit for power. Equal to 1,000,000,000 Watts (1,000 MW). [2]
The gigawatt is classified as an International System of Units (SI) unit of power. Gigawatts can be abbreviated as GW; for example, 1 gigawatt can be written as 1 GW.
In the metric system, "giga" is the standard SI prefix for billions, or 10⁹. This makes the gigawatt (GW) a convenient decimal multiple of the watt (W).
In practice, gigawatts (GW) 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 kilowatts (kW) and gigawatts (GW), keep full floating-point precision (1 kW = 0.000001 GW; 1 GW = 1,000,000 kW) during intermediate calculations and round only the final gigawatt figure to match your instrument tolerance.
