Horsepower to kilowatts (hp to kW)

The calculator allows you to convert horsepower to kilowatts (hp to kW).

Perform the reverse calculation: kW to hp

1 horsepower = 0.745699872 kilowatt (approximately equal to)
1 kilowatt = 1.341022 horsepower (approximately equal to)

To convert horsepower to kilowatts, multiply by 0.745699872 (approximately).

Examples

Convert 100 hp to kW:
100 hp = 100 x 0.745699872 = 74.57 kW

Convert 50 hp to kW:
50 hp = 50 x 0.745699872 = 37.28 kW

Convert 200 hp to kW:
200 hp = 200 x 0.745699872 = 149.14 kW

Horsepower

Horsepower (hp) is a unit of power that is commonly used to express the power output of engines and motors. It was originally defined by the Scottish engineer James Watt in the late 18th century as the amount of power needed to lift 550 pounds (250 kilograms) at a rate of one foot (0.3 meters) per second. This unit of measurement was based on the power output of a typical draft horse, which Watt used as a comparison to the steam engines he was developing. Today, horsepower is defined as 746 watts, which is approximately equivalent to the power output of a small car engine. This definition was established by the International System of Units (SI), which is the modern metric system used throughout the world. However, horsepower is still widely used in the United States and other countries that have not fully adopted the SI system.

The symbol for horsepower is "hp". There are many different types of horsepower measurements. The two most common types both measure electric horsepower: imperial horsepower (also called mechanical horsepower) and metric horsepower.

Kilowatt

A kilowatt (kW) is a unit of power in the International System of Units (SI). One kilowatt is equal to 1 000 watts or 1 kilojoule per second. "Kilo" is a prefix used in the International System of Units (SI) to denote a factor of 1 000. The prefix "kilo" is abbreviated with the letter "k" and is used to modify the base unit to which it is attached, such as meter, gram or watt.

The symbol for kilowatt (kW) is simply "kW". The "k" represents the prefix "kilo", which means 1 000, and the "W" represents the unit of power, the watt. So the kilowatt is a measure of power that is equal to 1 000 watts.
