Frequently Asked Questions
-
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.
