What does Pferdestärke (ps) represent?

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

When should I use Petajoule/second (PJ/s) as a power unit?

Petajoule/second (PJ/s) is appropriate for describing extremely large power flows such as national energy production or astrophysical power budgets.

Why are converted values from ps to PJ/s so small?

Because PJ/s measures vastly larger power scales, converting the relatively small mechanical power unit ps results in very small decimal numbers.
