Convert 15 KW to PS

KW and PS are both indicators of performance, especially for vehicles. Cars are still advertised with horsepower figures, even though KW is the official figure. It is therefore useful to enter values such as B. Quickly converting 15KW to PS.

The power of cars may officially only be given in KW.

PS as an outdated performance indicator

HP, i.e. the specification of the power of engines in horsepower, is an officially long outdated, but still widespread power specification. We automatically connect you to the performance of motor vehicles. Due to the long tradition of this specification, it is easier for us to compare performances given in horsepower.
In fact, KW (kilowatts) is the official power rating for engines and other equipment. PS may only be issued together with KW, it may no longer serve as a description of services alone. It is therefore important to be able to convert the KW data if you want to continue to use the old HP data for comparison purposes.

Conversion of 15KW to PS

The exact conversion shows that 1KW is exactly 1.359621617PS. However, since this value cannot be calculated in the head, there are approximation formulas that simplify the calculation in the head. According to the exact calculation, 15KW is 20.39PS.

The simplest formula says that 3KW is 4HP. However, this formula has a deviation of approx. 2 percent. Nevertheless, for a quick conversion and comparison, a 2% deviation is normally negligible. 15KW would be 20PS. In a comparison, the missing 0.4PS would probably be irrelevant.
Further, more precise approximation formulas are 11KW = 15PS (approx. 0.3% deviation) and 25KW = 34PS (approx. 0.03% deviation). Both formulas reduce the percentage deviation to a minimum, but are again significantly worse to calculate in the head. In the vast majority of cases, you should therefore get good results with the 1st Achieve approximation formula.
