Convert Metric horsepower to Megawatts
1 metric horsepower is 0.000735 MW. One metric horsepower is exactly 0.00073549875 megawatts.
One metric horsepower is 7.3550 × 10^-4 megawatts. To convert metric horsepower to megawatts, multiply by 7.3550 × 10^-4; to go the other way, divide by 7.3550 × 10^-4 or multiply by 1359.6216. The factor is exact rather than rounded: it follows from NIST Special Publication 811. Exactly 75 kilogram-force metres a second, which is 1.4% less than mechanical horsepower.

How do you convert metric horsepower to megawatts?
- 1.Take the measurement in metric horsepower.
- 2.Multiply by 7.3550 × 10^-4 — that is how many megawatts fit in one metric horsepower.
- 3.To go back the other way, divide by 7.3550 × 10^-4, or multiply by 1359.6216.
Worked example: 25 metric horsepower to megawatts
- Formula
- PS × 7.3550 × 10^-4 = MW
- Arithmetic
- 25 × 7.3550 × 10^-4 = 0.018387 MW
- Answer
- 25 PS = 0.018387 MW
The factor is rounded for display; the figure above is computed from the full value.

What is a metric horsepower?
Exactly 75 kilogram-force metres a second, which is 1.4% less than mechanical horsepower. A German car quoted at 150 PS is 148 hp, and the difference is the definition rather than the engine.
What is a megawatt?
A million watts. Generating plant and grid capacity are quoted in it: one megawatt runs roughly 750 homes in the US at average draw.
How many megawatts are in a metric horsepower?
One metric horsepower is 7.3550 × 10^-4 megawatts. Going the other way, one megawatt is 1359.6216 metric horsepower. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
