What is an attowatt used to measure?

An attowatt measures extremely small power levels, such as optical power from single-photon detectors or power dissipation in nanoscale devices.

How do I convert attowatts to nanowatts?

You multiply the attowatt value by 1e-9 to get the equivalent power in nanowatts.

Why convert attowatts to nanowatts?

Converting to nanowatts expresses ultra-small power measurements in a more manageable scale suitable for instrumentation and analysis in precision electronics and photonics.
