Conversion between mechanical horsepower and milliwatts
You can easily convert between mechanical horsepower [hp(I)] and milliwatts [mW] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Milliwatts [mW] = mechanical horsepower [hp(I)] * 272.155422 * 2,739.97801
- Mechanical horsepower [hp(I)] = milliwatts [mW] ÷ 272.155422 ÷ 2,739.97801
Conversion between mechanical horsepower and watts
The fastest and easiest way to convert between mechanical horsepower [hp(I)] and watts [W] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.
- Watts [W] = mechanical horsepower [hp(I)] * 27.2155422 * 27.3997801
- Mechanical horsepower [hp(I)] = watts [W] ÷ 27.2155422 ÷ 27.3997801
Conversion between mechanical horsepower and kilowatts
The two formulas below provide an easy way to convert between mechanical horsepower [hp(I)] and kilowatts [kW]. To ensure precise conversion results, it is important to follow the correct order of math operations.
- Kilowatts [kW] = mechanical horsepower [hp(I)] * 0.272155422 * 2.73997801
- Mechanical horsepower [hp(I)] = kilowatts [kW] ÷ 0.272155422 ÷ 2.73997801
Conversion between mechanical horsepower and metric horsepower
You can easily convert between metric horsepower [PS] and mechanical horsepower [hp(I)] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Mechanical horsepower [hp(I)] = metric horsepower [PS] * 735.49875 ÷ 27.2155422 ÷ 27.3997801
- Metric horsepower [PS] = mechanical horsepower [hp(I)] ÷ 735.49875 * 27.2155422 * 27.3997801
Conversion between mechanical horsepower and kilojoules per minute
The fastest and easiest way to convert between mechanical horsepower [hp(I)] and kilojoules per minute [kJ/min] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.
- Kilojoules per minute [kJ/min] = mechanical horsepower [hp(I)] * 6.64498604 * 6.73319583
- Mechanical horsepower [hp(I)] = kilojoules per minute [kJ/min] ÷ 6.64498604 ÷ 6.73319583
