kw to hp

The easiest way to remember the kW to HP conversion formula so for calculating a kilowatt measurement to horsepower, use one of the formulas below.



One kilowatt is the power equal to 1,000 watts, or the energy consumption at a rate of 1,000 joules per second. A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI). The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt.



The term horsepower was adopted by Scottish inventor James Watt to measure the power output of his steam engine and to compare that power with that of horses horses. Horsepower were later used to measure the power output of piston and turbine engines and electrical motors.

The horsepower (hp) is the name of several non-metric units of power. In scientific discourse the term “horsepower” is rarely used because of the various definitions and the existence of an SI unit for power, the watt (W).

How to convert Kilowatts to Horsepower?


1 kW = 1.341022 hp(I)Electric Horsepower
1 kW = 1.340483 hp(E)Metric Horsepower
1 kW = 1.359622 hp(M)Boiler Horsepower

Kilowatts to mechanic / hydraulic horsepower:

One mechanic or hydraulic horsepower is equal to 0.745699872 kilowatts:
1 hp(I) = 745.699872 W = 0.745699872 kW
So the power conversion of kilowatts to horsepower is given by:
P(hp) = P(kW) / 0.745699872

Convert 10kW to mechanic horsepower:
P(hp) = 10kW / 0.745699872 = 13.41 hp

Kilowatts to electrical horsepower:

One electrical horsepower is equal to 0.746 kilowatts:
1 hp(E) = 746 W = 0.746 kW
So the power conversion of kilowatts to horsepower is given by:
P(hp) = P(kW) / 0.746

Convert 10kW to electrical horsepower:
P(hp) = 10kW / 0.746 = 13.405 hp

Kilowatts to metric horsepower:

One metric horsepower is equal to 0.73549875 kilowatts:
1 hp(M) = 735.49875 W = 0.73549875 kW
So the power conversion of kilowatts to horsepower is given by:
P(hp) = P(kW) / 0.73549875

Convert 10kW to metric horsepower:
P(hp) = 10kW / 0.73549875 = 13.596 hp

Uses of Kilowatt:

A kilowatt-hour measures the energy an appliance uses in kilowatts per hour. For example, if you clean a floors with a 1,000-watt vacuum cleaner for one hour, you consume 1 kWh of energy. Your kilowatt-hour consumption factors in how many watts your appliances use and how often you use them.

Uses of Horsepower:

Horsepower is an important specification for buyers to consider, as it speaks directly to performance. For a given vehicle, an engine with more horsepower and more torque will accelerate more quickly important for drivers who frequently use freeway on-ramps and offer greater towing reliability.
