What does exajoule per second measure?

Exajoule per second measures the rate of energy flow at 10^18 joules per second, used to describe extremely large, planetary or astrophysical energy rates.

Why convert exajoule/second to horsepower?

Converting to horsepower allows translation of immense SI power values into a familiar imperial unit used for mechanical and engine power ratings.

Is this conversion practical for everyday engine power ratings?

No, this conversion is mostly theoretical and used for scale comparisons, as exajoule per second values are too large for typical mechanical applications.
