What is a nanowatt used to measure?

A nanowatt quantifies very low power rates in electronics and photonics, such as power consumption of ultra-low-power microcontrollers and output levels from weak light sources.

What does an exawatt represent?

An exawatt measures extremely large power levels, often related to planetary or astrophysical scales like total solar power received by Earth or stellar luminosities.

Why convert nanowatts to exawatts?

This conversion helps understand and compare power values across vastly different magnitudes, bridging micro-scale energy devices and astronomical power phenomena.
