Horsepower to Kilowatt (HP to KW)

Knowing how horsepower connects to kilowatts is super helpful for stuff like cars and factory machines.

Horsepower is a unit of power that measures the rate at which work is done. It originated from the power output of horses.

A kilowatt is a unit of power equal to 1,000 watts. It is commonly used to measure electrical power.

The Magic Formula:

P(kW) = 0.7457 × P(hp)

Converting 10 horsepower to kilowatts:

P(kW) = 0.7457 × 10 hp = 7.457 kW

Your 10 hp engine is equivalent to 7.457 kilowatts!

The Simple Formula:

P(kW) = 0.746 × P(hp)

For a 10 hp electrical motor:

P(kW) = 0.746 × 10 hp = 7.46 kW

Your electrical motor uses 7.46 kilowatts!

European Standard Formula:

P(kW) = 0.7355 × P(hp)

For a 10 hp European machine:

P(kW) = 0.7355 × 10 hp = 7.355 kW

That’s 7.355 kilowatts in the metric system!
