What is electric horsepower used for?

Electric horsepower rates the power output of electric motors, commonly found on motor nameplates to indicate performance.

Why convert horsepower (electric) to joule/hour?

Converting to joule/hour helps analyze energy transfer rates over time, which is useful for understanding slow power consumption or thermal losses.

Is joule/hour a common unit for power?

Joule per hour is used primarily for expressing very low power levels and energy flows measured over hours, not for instantaneous power.
