What is Pferdestärke (ps)?

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

How is Joule/hour [J/h] used?

Joule per hour (J/h) measures energy transfer over time, useful for expressing low power levels such as thermal losses and standby power in scientific and engineering contexts.

Why might the conversion produce large numbers?

Because Joule/hour represents very low power values, converting from the much larger Pferdestärke unit results in very large numerical values.
