What Is a Megawatt?
A megawatt is a unit of power equal to 1,000,000 watts (W), the base unit for power. Equal to 1,000,000 Watts (1,000 kW). [1]
The megawatt is classified as a metric and SI-compatible unit of power. Megawatts can be abbreviated as MW; for example, 1 megawatt can be written as 1 MW.
In the metric system, "mega" is the standard SI prefix for millions, or 10⁶. This makes the megawatt (MW) a convenient decimal multiple of the watt (W).
In practice, megawatts (MW) 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 Horsepower?
A horsepower is a unit of power equal to 745.6998716 watts (W), the base unit for power. Imperial mechanical horsepower (550 ft·lbf/s ≈ 745.7 W). [2]
The horsepower is classified as a US customary and imperial unit of power. Horsepower can be abbreviated as hp; for example, 1 horsepower can be written as 1 hp.
When working with horsepower (hp) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, horsepower (hp) are widely used across standard power applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
When converting power between megawatts (MW) and horsepower (hp), keep full floating-point precision (1 MW = 1,341.0220896 hp; 1 hp = 0.0007457 MW) during intermediate calculations and round only the final horsepower figure to match your instrument tolerance.
