This converter allows you to convert metric horsepower [PS] to mechanical horsepower [hp(I)] or mechanical horsepower [hp(I)] to metric horsepower [PS]. 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 metric horsepower [PS] ≈ 0.9863 mechanical horsepower [hp(I)]1 mechanical horsepower [hp(I)] ≈ 1.0139 metric horsepower [PS]

Convert metric horsepower to mechanical horsepower

There are two simple ways to convert metric horsepower [PS] to mechanical horsepower [hp(I)]. In the first calculation method, the value in metric horsepower [PS] is divided by the rounded conversion factor of 1.0139. The second method multiplies the value in metric horsepower [PS] by the rounded conversion factor of 0.9863.

  • Mechanical horsepower [hp(I)] ≈ metric horsepower [PS] ÷ 1.0139
  • Mechanical horsepower [hp(I)] ≈ metric horsepower [PS] * 0.9863

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

  • Mechanical horsepower [hp(I)] = metric horsepower [PS] * 735.49875 ÷ 27.2155422 ÷ 27.3997801

Convert mechanical horsepower to metric horsepower

Converting mechanical horsepower [hp(I)] to metric horsepower [PS] is easy and can be done in two ways. The first method involves multiplication, in which the value in mechanical horsepower [hp(I)] is multiplied by the rounded conversion factor of 1.0139. The second variant is a division. Here, the value in mechanical horsepower [hp(I)] is divided by the rounded conversion factor of 0.9863.

  • Metric horsepower [PS] ≈ mechanical horsepower [hp(I)] * 1.0139
  • Metric horsepower [PS] ≈ mechanical horsepower [hp(I)] ÷ 0.9863

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

  • Metric horsepower [PS] = mechanical horsepower [hp(I)] ÷ 735.49875 * 27.2155422 * 27.3997801
