What does 1 exawatt represent?

1 exawatt is an SI unit of power equal to 10^18 watts, used to describe very large-scale energy transfer rates typically found in astrophysics and planetary science.

What is a millijoule per second used for?

A millijoule per second is a small power unit equal to 0.001 watts, commonly applied in measuring power in low-energy electronics and precise laboratory experiments.

Why convert exawatts to millijoule/second?

Converting helps compare extremely large power levels with very small ones, enabling better understanding across different scientific fields such as astrophysics and microelectronics.
