About Converting Metric horsepowers to Megawatts
Metric horsepower and Megawatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Metric horsepower is most often used for european and japanese vehicle engine power ratings (often shown as ps or cv).
Formula
megawatts = metric horsepowers × 0.00073549875
This factor comes from each unit's defined relationship to the category's base unit: 1 metric horsepower equals 735.49875 base units, and 1 megawatt equals 1000000 base units, so dividing one by the other gives the direct metric horsepower-to-megawatt factor of 0.00073549875.
Simple example
1 PS × 0.00073549875 = 0.0007354988 MW
1 metric horsepower = 0.0007354988 megawatts.
Real-world example
100 PS × 0.00073549875 = 0.073549875 MW
100 metric horsepowers = 0.073549875 megawatts.

Understanding the Metric horsepower
Metric horsepower (PS) measures power. Metric horsepower (PS/CV) is defined as exactly 735.49875 watts, the power to raise 75 kilograms one meter per second. It is classified as a Non-SI unit (metric, automotive).
Where it's used: Continental Europe, Japan, and other metric-system automotive markets
Uses of the Metric horsepower today
- European and Japanese vehicle engine power ratings (often shown as PS or CV)
- Motor and machinery power specifications in metric countries
History of the Metric horsepower
Metric horsepower emerged in continental Europe in the 19th century as engineers sought a metric-system analog to Watt's English horsepower, defining it via a round figure (75 kgf·m/s) convenient in metric calculations. It remains the standard automotive power unit across much of Europe and Asia, labeled PS (German 'Pferdestärke') or CV (French/Italian 'cheval-vapeur').
Historical origin. Metric horsepower was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many megawatts are in 1 metric horsepower?
1 metric horsepower equals 0.0007354988 megawatts, using the exact defined conversion factor rather than an estimate.
How do I convert metric horsepower to megawatt?
Multiply the metric horsepower value by 0.00073549875. The converter above does this instantly to whatever precision you set.
How do I convert megawatt back to metric horsepower?
Use the reverse factor: 1 megawatt equals 1,359.621617 metric horsepowers. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric horsepower?
Metric horsepower (PS) measures power. Metric horsepower (PS/CV) is defined as exactly 735.49875 watts, the power to raise 75 kilograms one meter per second. It is classified as a Non-SI unit (metric, automotive).
What is a megawatt?
