Convert Megawatts to Horsepower
1 megawatt is 1,341.02209 hp. One megawatt is exactly 1341.0220896 horsepower.
One megawatt is 1341.0221 horsepower. To convert megawatts to horsepower, multiply by 1341.0221; to go the other way, divide by 1341.0221 or multiply by 7.4570 × 10^-4. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A million watts.

How do you convert megawatts to horsepower?
- 1.Take the measurement in megawatts.
- 2.Multiply by 1341.0221 — that is how many horsepower fit in one megawatt.
- 3.To go back the other way, divide by 1341.0221, or multiply by 7.4570 × 10^-4.
Worked example: 25 megawatts to horsepower
- Formula
- MW × 1341.0221 = hp
- Arithmetic
- 25 × 1341.0221 = 33,525.55224 hp
- Answer
- 25 MW = 33,525.55224 hp
The factor is rounded for display; the figure above is computed from the full value.

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.
What is a horsepower?
Mechanical horsepower: exactly 550 foot-pounds of work every second, the figure James Watt settled on to sell engines against pit ponies. US vehicle and motor ratings use it.
How many horsepower are in a megawatt?
One megawatt is 1341.0221 horsepower. Going the other way, one horsepower is 7.4570 × 10^-4 megawatts. 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.
