Welcome to 1 hp to kW, our post covering the conversion of 1 horsepower to kilowatts.

1 horsepower usually means 1 mechanical hp or 1 metric hp, used, for example, to describe the power of cars in the US (converter default), respectively Europe.

However, it could also mean 1 electric hp or 1 boiler hp.

What’s more is that in case of electric horsepower the equivalent of 1 hp in kilowatts in the US slightly differs from the result of the conversion in Europe.

Read on to learn how to convert the work over time, taking into account the following short forms:
• 1 mechanical hp, aka 1 imperial hp, is denoted as 1 hp(I)
• 1 metric hp in short form is 1 hp(M)
• 1 electric hp in the US is abbreviated as 1 hp(E) US
• 1 electric hp in Europe in shortened form is 1 hp(E) Europe

1 horsepower in the context of US cars means mechanical horsepower, hp(I), whereas 1 horsepower in the context of automobiles in Europe means metric horsepower, hp(M).

## 1 HP to kW Conversion and Formulas

Here we use the formulas explained on our home page to obtain the following results which are rounded to two decimals:

• hp(I): [kW] = [1] × 0.74569987158227022 = 0.75 kW
• hp(M): [kW] = [1] × 0.73549875 = 0.74 kW
• hp(E) US: [kW] = [1] × 0.746 = 0.75 kW
• hp(E) Europe: [kW] = [1] × 0.735 = 0.74 kW
• hp(S): [kW] = [1] × 9.810657 = 9.81 kW
