What is electric horsepower?

Electric horsepower is a unit of power used to rate electric motors, defined as exactly 746 watts, representing the energy conversion rate of one horsepower produced by an electric machine.

What does exajoule/second measure?

Exajoule per second (EJ/s) measures extremely large energy flow rates at the scale of 10^18 joules per second, used for planetary or astrophysical energy comparisons.

Why convert horsepower (electric) to EJ/s?

Converting to EJ/s allows expressing motor power on large scales useful in climate studies and astrophysics, where traditional units are too small to provide meaningful context.
