What is a centiwatt (cW)?

A centiwatt is a unit of power equal to one hundredth of a watt (1 cW = 10⁻² W) used to measure very low-power systems.

What does exawatt (EW) represent?

An exawatt is an SI unit of power equal to 10¹⁸ watts, often used for describing very large power levels like planetary or astrophysical energy flows.

Why is converting cW to EW useful?

It helps contextualize extremely low-power measurements by comparing them to planetary or astrophysical-scale power units.

Is the converted value from cW to EW easy to interpret?

Due to the vast difference in scale, the resulting values are extremely small decimals, requiring scientific notation and appropriate context.
