An exawatt (EW) is an SI unit of power equal to 10^18 watts, used to describe extremely large power levels often found in planetary or astrophysical phenomena.

What does a centiwatt measure?

A centiwatt (cW) equals one hundredth of a watt and quantifies very low power levels typically found in ultra-low-power electronics and sensor devices.

Why convert between exawatt and centiwatt units?

Users convert from exawatt to centiwatt to translate very large-scale power measurements into very small-scale units, facilitating comparison across vastly different power magnitudes.
