About Hp to kW Converter

Welcome to our new easy to use hp to kW converter. It was created for those users and our friends who are in need of very fast and easy hp-to-kW conversions. For those who need to know the power of their automobile, engine, electric motor or turbine in kilowatts, this online tool can turn into a great, fast and effective solution. In contrast to other complicated and bulky general convertors, our tool is easy to use and very fast.

Historically, horsepower was the first power unit emerged and widely used around the world. In the middle ages, a horse was one of the most important elements of almost every household, that is why starting from the 18th century, with the development of first steam engines, a horsepower was chosen as a great comparative unit of power.

Horsepower to Kilowatts Calculation

1 hp = 33,000 ft·lbf / minutes
1 hp = 33,000 ft·lbf / 60 seconds
1 hp = 550 x 0.3048 x 0.453592376 m·kgf/s
1 hp = 76.04022591264 kgf·m/s
applying gravity constant
1 hp = 745.699872 N·m/s

by definition
1 ft = 0.3048 m
1 lb = 0.453592376 kg

we need kilowatts
1 kW = 1000 W

1 hp = 745.699872 N·m/s · (1/1000)
1 hp = 0.745699872 kW

In our times, there are a few types of horsepower are used. In those countries where the Imperial system is practiced, mechanical or imperial horsepower is used, which is approximately equal to 745.7 watts. Electrical horsepower is a unit that is equivalent to 746 watts. It is usually used for rating electric motors and engines. There is also metric horsepower which has been used in Europe since the beginning of the 19th century. It is equivalent to roughly 735.5 watts.

In contrast to other similar scientific calculators, our horsepower to kilowatts convertor is a very simple tool available online at any moment when one may need to make this conversion. All you need is to enter the value of horsepower you want to convert, choose the type of horsepower you’re operating with, and press the Convert button.
