How to Convert Gigawatts to Metric Horsepower
To convert gigawatts to metric horsepower, multiply the power by the following conversion ratio: 1,359,621.6173039 metric horsepower/gigawatt.
Since one gigawatt is equal to 1,359,621.6173039 metric horsepower, you can use this simple formula to convert:
The power in metric horsepower is equal to the power in gigawatts multiplied by 1,359,621.6173039.
For example, here's how to convert 5 gigawatts to metric horsepower using the formula above.
How Many Metric Horsepower Are in a Gigawatt?
There are 1,359,621.6173039 metric horsepower in a gigawatt, which is why we use this value in the formula above.
Our gigawatt to horsepower calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Gigawatts and metric horsepower are both units used to measure power. Keep reading to learn more about each unit.
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). [1]
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.
What Is a Horsepower?
A horsepower is a unit of power equal to 735.49875 watts (W), the base unit for power. Metric horsepower (75 kgf·m/s = 735.49875 W). [2]
The horsepower is classified as a metric and SI-compatible unit of power. Metric Horsepower can be abbreviated as PS; for example, 1 horsepower can be written as 1 PS.
When working with metric horsepower (PS) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, metric horsepower (PS) are widely used across standard power applications within SI metric workflows, engineering documentation, and technical data sheets.
When converting power between gigawatts (GW) and metric horsepower (PS), keep full floating-point precision (1 GW = 1,359,621.6173039 PS; 1 PS = 0.000000735 GW) during intermediate calculations and round only the final horsepower figure to match your instrument tolerance.
