What does one milliwatt represent?

A milliwatt is one thousandth of a watt and indicates the rate of energy transfer of one joule per second, commonly used for low power electrical and optical devices.

When should I use attowatts instead of milliwatts?

Attowatts are used to measure extremely small power levels in contexts like ultra-sensitive detectors, nanoelectronics, and experimental physics.

Why do conversion results to attowatts involve very large numbers?

Because one attowatt is 10⁻¹⁸ watts, converting from milliwatts (10⁻³ watts) produces values multiplied by 10¹⁵, resulting in large numerical results.
