# 159 cc is how many horsepower

## Conversion of kilowatts kW into PS

Updated on by Stefan Banse

If you follow a conversation among non-car enthusiasts, the question often arises of how much horsepower the vehicle has. A car professional would never ask this question. The power of a vehicle is officially stated, i.e. in the vehicle registration document or when a car is sold, in kW, i.e. kilowatts. We will explain why this is so later.

### History of the old horsepower rating

But where does the confusion come from, why does the unit PS persist so stubbornly? The horsepower PS is an outdated unit that is still often found in Germany. It expresses the performance of a vehicle. The term horse power goes back to James Watt. The unit of horsepower should indicate how many horses a machine can replace.

Although PS has not been an official legal unit in Germany since 1978, it is still used primarily for internal combustion engines. An EU directive from 2009 states that the use of the unit PS is still permitted today. So the term will certainly not die out among car enthusiasts.

### Formulas for converting between kW and PS

If you do a calculation between kW and PS, you will now find the formulas for both output values.

Determine height kW from PS:
PS / 1,35962

Determine the HP from kW:
kW * 1.35962
