An exawatt (EW) is an SI unit of power equal to 10^18 watts, representing a very large rate of energy transfer per second.

How is joule per hour different from watt?

Joule per hour measures energy transfer per hour, relating to watts by the factor 1 J/h = 1/3600 W, thus representing a much slower energy rate.

Why convert from exawatt to joule per hour?

This conversion helps express extremely large power in terms of energy transferred over time scales relevant for comparisons and engineering calculations.
