Mechanical, Metric, and Electric Horsepower

"Horsepower" has more than one definition, which is why conversions can differ slightly between sources. Mechanical (imperial) horsepower — the value this converter uses — equals 745.7 watts, so 1 kW = 1.34102 hp. Metric horsepower (written PS in Germany or CV in France) equals 735.5 watts, giving 1 kW = 1.35962 PS. Electric horsepower, used for motor ratings, is defined as exactly 746 watts. James Watt originally chose the unit to compare his steam engines with the draft horses they replaced.

FAQ

How many horsepower are in one kilowatt?

One kilowatt equals approximately 1.34102 mechanical horsepower.

Why do electric cars list power in both kW and hp?

Kilowatts are the SI standard for power, while horsepower is more familiar to buyers in the US and UK. Manufacturers list both so shoppers can compare electric motors with traditional combustion engines.

Is metric horsepower the same as mechanical horsepower?

No. Metric horsepower (PS or CV) equals 735.499 W, while mechanical horsepower equals about 745.7 W. This converter uses mechanical horsepower (1 kW = 1.34102 hp).

How do I convert my EV motor rating to horsepower?

Multiply the kilowatt rating by 1.34102. For example, a 150 kW motor produces about 201.2 hp.

How many kilowatts is 200 horsepower?

Divide horsepower by 1.34102: 200 hp ÷ 1.34102 ≈ 149.1 kW.

Is one horsepower exactly 745.7 watts?

Mechanical (imperial) horsepower is defined as 745.6998716 watts. Rounding gives 745.7 W, which produces the 1 kW = 1.34102 hp factor this converter uses.

How much horsepower does a home need?

Household appliances are rated in kilowatts, not horsepower, but for comparison a 3 kW kettle is about 4 hp and a 7.4 kW EV home charger draws roughly 9.9 hp of electrical power.

How many horsepower are in 1 kilowatt?

1 kW equals 1.34102 hp.

How do you convert kilowatts to horsepower?

Multiply the kilowatt value by 1.34102. Formula: hp = kW × 1.34102.

How many horsepower are in 5 kilowatts?

5 kW = 6.7051 hp.

How do you convert horsepower back to kilowatts?

Use the inverse formula: kW = hp ÷ 1.34102. For example, 1 hp = 0.745701 kW.

What is the difference between Kilowatt and Horsepower?

A kilowatt equals 1,000 watts. One mechanical horsepower equals exactly 745.6998715822702 watts; one metric horsepower equals exactly 735.49875 watts.
