How to Convert Kilowatts to Mechanical Horsepower

To convert a kilowatt measurement to a mechanical horsepower measurement, multiply the power by the conversion ratio. One kilowatt is equal to 1.341022 mechanical horsepower, so use this simple formula to convert:

mechanical horsepower = kilowatts × 1.341022

The power in mechanical horsepower is equal to the kilowatts multiplied by 1.341022.

For example, here's how to convert 5 kilowatts to mechanical horsepower using the formula above.
5 kW = (5 × 1.341022) = 6.70511 hp(I)

Kilowatts and mechanical horsepower are both units used to measure power. Keep reading to learn more about each unit of measure.


One kilowatt is the power equal to 1,000 watts, or the energy consumption at a rate of 1,000 joules per second.

The kilowatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "kilo" is the prefix for 103. Kilowatts can be abbreviated as kW, for example 1 kilowatt can be written as 1 kW.

Mechanical Horsepower

Mechanical horsepower is often used to measure the output of engines and motors in North America. One mechanical horsepower is equal to 745.69987158227022 watts.

The mechanical horsepower is a US customary and imperial unit of power. Mechanical horsepower can be abbreviated as hp(I), for example 1 mechanical horsepower can be written as 1 hp(I).

Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

Here is a list of some of the common metric prefixes:

  • “kilo” – 1,000x larger
  • “hecto” – 100x larger
  • “deca” – 10x larger
  • “deci” – 10x smaller
  • “centi” – 100x smaller
  • “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”
The u in Until refers to the base unit.
