The Mechanical horsepower Converter supports 24 different power units. This makes it possible to convert freely between mechanical horsepower [hp(I)], metric, Anglo-American, and other power units. All power values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.


Conversion of mechanical horsepower

In order to convert mechanical horsepower [hp(I)] into another unit of measurement, a conversion value is required. This value can be determined using a conversion table. However, the table is relatively large, confusing, and difficult for inexperienced users to understand. The tool below provides a solution to this problem by allowing the rounded conversion values for mechanical horsepower [hp(I)] to be queried directly from the conversion table.

Determine conversion factor

≈ 745.6999
Calculation example:
Watts = Mechanical horsepower * 27.2155422 * 27.3997801
Mechanical horsepower = Watts ÷ 27.2155422 ÷ 27.3997801

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
