Conversion and Formulas
Here we use the formulas explained on our home page to obtain the following results which are rounded to two decimals:
- hp(I): [kW] =  × 0.74569987158227022 = 298.28 kW
- hp(M): [kW] =  × 0.73549875 = 294.2 kW
- hp(E) US: [kW] =  × 0.746 = 298.4 kW
- hp(E) Europe: [kW] =  × 0.735 = 294 kW
- hp(S): [kW] =  × 9.810657 = 3924.26 kW
