What does 1 millijoule per second represent?

It is a unit of power equivalent to 0.001 joules per second or 1 milliwatt, typically used for low-power systems.

What is an exawatt used to measure?

An exawatt measures extremely large power levels, such as planetary energy flows or astrophysical power outputs.

Why are converted values from mJ/s to EW so small?

Because 1 millijoule/second is much smaller than 1 exawatt, resulting in very small numbers after conversion.
