This converter allows you to convert mechanical horsepower [hp(I)] to megawatts [MW] or megawatts [MW] to mechanical horsepower [hp(I)]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 mechanical horsepower [hp(I)] ≈ 7.457 * 10-4 megawatts [MW]1 megawatt [MW] ≈ 1,341.0221 mechanical horsepower [hp(I)]

Convert mechanical horsepower to megawatts

There are two simple ways to convert mechanical horsepower [hp(I)] to megawatts [MW]. In the first calculation method, the value in mechanical horsepower [hp(I)] is divided by the rounded conversion factor of 1,341.0221. The second method multiplies the value in mechanical horsepower [hp(I)] by the rounded conversion factor of 7.457 * 10-4.

  • Megawatts [MW] ≈ mechanical horsepower [hp(I)] ÷ 1,341.0221
  • Megawatts [MW] ≈ mechanical horsepower [hp(I)] * 7.457 * 10-4

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of mechanical horsepower [hp(I)] to megawatts [MW] can be achieved using the following calculation method.

  • Megawatts [MW] = mechanical horsepower [hp(I)] * 27.2155422 * 27.3997801 ÷ 106

Convert megawatts to mechanical horsepower

Converting megawatts [MW] to mechanical horsepower [hp(I)] is easy and can be done in two ways. The first method involves multiplication, in which the value in megawatts [MW] is multiplied by the rounded conversion factor of 1,341.0221. The second variant is a division. Here, the value in megawatts [MW] is divided by the rounded conversion factor of 7.457 * 10-4.

  • Mechanical horsepower [hp(I)] ≈ megawatts [MW] * 1,341.0221
  • Mechanical horsepower [hp(I)] ≈ megawatts [MW] ÷ (7.457 * 10-4)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of megawatts [MW] to mechanical horsepower [hp(I)] can be achieved using the following calculation method.

  • Mechanical horsepower [hp(I)] = megawatts [MW] ÷ 27.2155422 ÷ 27.3997801 * 106
