200 HP to kW: Convert Horsepower to Kilowatts
200 hp is 149.14 kW and 202.78 PS. The 0.7457 multiplier, a full conversion table, and where each unit is used.
At a glance
The Conversion
200 horsepower equals 149.14 kilowatts and 202.78 metric horsepower (PS). Multiply any hp figure by 0.7457 to get kW, or by 1.0139 to get PS. Going the other way, divide kW by 0.7457 to recover horsepower — a 150 kW electric motor is a 201.2 hp unit.

Why Two Kinds of Horsepower?
Mechanical horsepower (hp) is the American standard at 550 foot-pounds per second, while PS (Pferdestarke) is the metric version used in Europe and Asia. They differ by about 1.4%, so a car advertised at 200 PS actually makes 197.3 hp — close enough that many listings treat them as interchangeable, but the numbers are not identical.
Where kW Shows Up
Kilowatts are the SI unit of power: electric vehicles, charging equipment, and most non-US spec sheets quote kW. If you are comparing an EV rated at 150 kW with a gas car rated at 200 hp, the gas car is slightly less powerful at 149.1 kW. Use the calculator above for torque-and-RPM work, or just apply the 0.7457 multiplier for quick conversions.
Frequently Asked Questions
How many kW is 1 hp?
One mechanical horsepower is 0.7457 kW, so multiply any hp figure by 0.7457 to convert.
Is PS the same as hp?
Nearly. One hp equals 1.0139 PS, a difference of about 1.4%, so spec sheets often round between them.
How do I convert kW back to hp?
Divide kilowatts by 0.7457. A 100 kW motor equals about 134.1 hp.
Does an electric car's kW rating match engine hp?
It measures the same thing — power. A 200 kW EV motor produces about 268 hp (200 / 0.7457).
