What is Pferdestärke (ps)?

Pferdestärke (PS) is a metric horsepower unit historically used in German-speaking countries to express mechanical power, equivalent to 735.49875 watts.

Why convert ps to kilocalorie (IT)/hour?

Converting ps to kcal/h is useful for interpreting engine power ratings in terms of thermal energy rates, which are relevant for heating, cooling, and metabolic energy analyses.

Is Pferdestärke an SI unit?

No, Pferdestärke is not an SI unit but remains common in certain regional and historical mechanical power measurements.

What does 1 kcal(IT)/hour represent?

It represents the rate of energy transfer equal to one International-Table kilocalorie per hour, approximately 1.163 watts.

Can I use this conversion for modern engine power ratings?

Yes, it is applicable where power is rated in Pferdestärke, especially in Germany and nearby markets, to translate into thermal energy units.
