Megawatts to Horsepower formula
Converting megawatts to horsepower is a single multiplication by 1341.02209.
hp = MW × 1341.02209
Why this factor: the megawatt and the horsepower are both defined against the watt, so dividing one definition by the other gives 1341.02209 directly. Both definitions are set out in full below.
To go the other way, divide by 1341.02209 — or use the Horsepower to Megawatts converter, which is the same calculation reversed.
Worked example
Given 150 MW, multiplying by 1341.02209 yields 201153.313439 hp.
150 MW × 1341.02209 = 201153.313439 hp
The converter above does this for any value you type, in either direction.
What is a megawatt?
A megawatt is one million watts, the unit of power-station and grid-scale capacity.
Definition: Exactly 1×10⁶ watts.
Where it is used: Power plant and wind farm output, data-centre capacity, and grid demand.
What is a horsepower?
Mechanical horsepower is the traditional English-speaking unit of engine power.
Definition: Defined as 550 foot-pounds per second, which is about 745.700 watts.
Where it is used: US and UK car, motorcycle and small-engine power ratings.
Worth knowing: Distinct from metric horsepower (PS), which is about 1.4% smaller — so the same engine scores slightly higher in PS than in hp.
Megawatts vs Horsepower
The megawatt is a metric unit while the horsepower is an imperial unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
