Horsepower to kilowatt (Hp To Kw) Converter

Horsepower to kW Calculator

Convert horsepower (HP) to kilowatts (kW).

What is Horsepower (HP)?

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

  • Imperial/Mechanical HP = 745.7 watts (commonly used in US/UK)
  • Electrical HP = 746 watts (used in electrical systems)
  • Metric HP = 735.5 watts (used in many European countries)

What is a Kilowatt (KW)?

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

  • 1 KW = 1000 watts
  • 1 KW = 1000 joules per second
  • It’s the standard unit for measuring electrical power

Three Methods Of Converting Horsepower to Kilowatts

1. Imperial/Mechanical HP to KW

The Magic Formula:

P(kW) = 0.7457 ร— P(hp)

Example

Converting 10 horsepower to kilowatts:

P(kW) = 0.7457 ร— 10 hp = 7.457 kW

Your 10 hp engine is equivalent to 7.457 kilowatts!

2. Electrical HP to KW

The Simple Formula:

P(kW) = 0.746 ร— P(hp)

Example

For a 10 hp electrical motor:

P(kW) = 0.746 ร— 10 hp = 7.46 kW

Your electrical motor uses 7.46 kilowatts!

3. Metric HP to KW

European Standard Formula:

P(kW) = 0.7355 ร— P(hp)

Let’s Calculate

For a 10 hp European machine:

P(kW) = 0.7355 ร— 10 hp = 7.355 kW

That’s 7.355 kilowatts in the metric system!
