What does a femtowatt measure?

A femtowatt is an SI derived unit of power equal to 10⁻¹⁵ watt, used to quantify extremely small energy transfer rates, often in nanoscale or sensitive measurement systems.

Where is kilocalorie (th)/second commonly used?

Kilocalorie (th)/second measures the rate of heat transfer and is commonly applied in thermal power ratings, calorimetry, heating equipment, and HVAC system design.

Why convert femtowatt to kilocalorie (th)/second?

Such conversion helps express very low-level electrical power measurements in terms of thermal power for applications that involve heat transfer analysis and interdisciplinary engineering contexts.
