What does a nanowatt measure?

A nanowatt is a unit of power equal to 10⁻⁹ watts, typically used to measure very low power levels like in ultra-low-power electronics or photonics.

What scale of energy does exajoule per second represent?

Exajoule per second measures extremely large energy flows, such as planetary or stellar-scale power, equivalent to 10¹⁸ watts.

Why convert from nanowatt to exajoule per second?

This conversion helps relate tiny power measurements to massive energy flows for contextual understanding across vastly different scales.
