What is a femtowatt used to measure?

A femtowatt measures extremely small power levels often seen in nanoscale electronics, radio astronomy, and ultra-sensitive photodetection.

Why convert femtowatt to Btu (th)/minute?

Converting femtowatt to Btu (th)/minute helps relate very small power measurements to conventional thermal power units important in HVAC and industrial heating systems.

Can this conversion be used for precise engineering calculations?

Because of the vast difference in unit scales, this conversion is better suited for comparison and understanding rather than highly precise engineering use.
