What is a femtowatt used to measure?

A femtowatt measures extremely small power levels often found in radio astronomy, nanoscale electronics, and sensitive photodetection systems.

Why convert femtowatt to erg per second?

Converting femtowatt to erg per second helps express power measurements in the CGS system, which is still used in astrophysics and older scientific contexts.

Are there challenges when converting between femtowatt and erg/second?

Yes, since these units belong to different measurement systems, users must be careful with unit consistency and consider possible noise and uncertainty for small values.
