Terawatts and metric horsepower 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 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 terawatts (TW) and metric horsepower (PS), keep full floating-point precision (1 TW = 1,359,621,617.3039043 PS; 1 PS = 7.354988e-10 TW) during intermediate calculations and round only the final horsepower figure to match your instrument tolerance.
