What is the difference between metric and mechanical hp?

Metric hp (PS, cv, hk) is ~735.5 W, and mechanical (hp, imperial) is ~745.7 W. In Russia, the metric system is used.

How to convert kW to hp?

You need to divide the number of kilowatts by 0.7355 or multiply by 1.36. For example, 100 kW is approximately 136 hp.

One metric horsepower is approximately 0.7355 kW (735.5 Watts).

🚗 Engine power converter: hp. in kW

Converting horsepower to kilowatts is a common task for car owners. In Russia, in the PTS (Vehicle Passport), power is indicated in both quantities, but exact conversion is often required to calculate transport tax or obtain insurance.

⚙️ Translation formula:
1 Horsepower (metric) ≈ 0.7355 kW
1 Kilowatt ≈ 1.3596 hp

Engine🚗 Calculation of theoretical engine power This calculator allows you to find out the potential of the engine (in horsepower and kilowatts), based on its physical parameters: volume, number of cylinders and compression ratio.

Engine🏎️ Find out the real power, not the nameplate Factory specifications often do not coincide with reality - engines wear out, and tuning changes parameters.

Frequently asked questions (FAQ)

🔹 Why are the values different in different calculators?

There is a "Metric HP" (used in the Russian Federation and Europe) and “Mechanical HP.” (used in US/UK). Our calculator uses the metric standard (1 hp = 735.5 W), as it is adopted in Russian legislation.

🔹 Why translate hp. in kW?

In Russia tax is calculated based on horsepower. However, in a number of countries (for example, Australia) or for electric vehicles (Tesla, etc.), the main characteristic is Kilowatt. This is also necessary for registering imported cars.

🔹 How many kilowatts are in 1 horsepower?

Exact value: 0.73549875 kW. For a rough calculation in your head, you can multiply the number of horses by 0.74.
