Convert Metric Horsepower to Megawatts
Metric horsepower to megawatts is the conversion you need when the power runs large — big industrial engines, generators, or ship propulsion rated in PS — and megawatts are the natural scale. One metric horsepower is exactly 0.00073549875 megawatts, so the megawatt number comes out very small until the horsepower count is large.

The formula
To convert metric horsepower to megawatts, multiply the number of metric horsepower by 0.00073549875:
megawatts = metric horsepower × 0.00073549875
A worked example
Say you have a 1000 PS engine and want its power in megawatts:
1000 × 0.00073549875 = 0.73549875 MW
So 1000 metric horsepower is exactly 0.73549875 megawatts.
Why the number is exact
Metric horsepower is a defined unit, not a rounded one. One metric horsepower (PS, or CV, from the German "Pferdestärke") is defined as exactly 75 kilogram-force meters per second, which is exactly 735.49875 watts — that is, exactly 0.00073549875 megawatts. Because the definition fixes the value precisely, converting from metric horsepower to megawatts is exact, with nothing rounded away.
When you'll use it
Sizing up large industrial engines, generators, or ship propulsion that are rated in PS but compared at megawatt scale, and any time a metric-horsepower figure is big enough that megawatts are the tidier unit.
Frequently asked questions
How many megawatts are in one metric horsepower?
Exactly 0.00073549875 megawatts. Metric horsepower is defined as 75 kgf·m/s, which is exactly 735.49875 W, or 0.00073549875 MW — nothing is rounded.
How much metric horsepower makes one megawatt?
Since one metric horsepower is exactly 0.00073549875 MW, it takes roughly 1,360 PS to reach one megawatt. Megawatts only become the handy unit once you're dealing with large industrial or marine power.
Is the metric horsepower to megawatts conversion exact?
Yes. Metric horsepower is defined as exactly 75 kgf·m/s, which is exactly 0.00073549875 MW, so the conversion is exact with nothing rounded away.
