A femtowatt (fW) is an SI derived unit of power equal to 10⁻¹⁵ watt, representing extremely small energy transfer rates.

Why convert femtowatt to kilocalorie (th)/minute?

Conversion helps express ultra-low power levels in terms of thermal energy transfer or metabolic energy expenditure for easier interpretation.

Is kilocalorie (th)/minute suitable for all power scales?

Kilocalorie (th)/minute is generally used for macroscopic thermal powers and may be less practical for femtowatt-level values without precise instrumentation.
