Thermal Conductivity of Conduction in Conduction Formulas

No, the Thermal Conductivity of Conduction, measured in Thermal Conductivity cannot be negative.

Thermal Conductivity of Conduction is usually measured using the Watt per Meter per K[W/(m*K)] for Thermal Conductivity. Kilowatt per Meter per K[W/(m*K)], Calorie (IT) per Second per Centimeter per °C[W/(m*K)], Kilocalorie (th) per Hour per Meter per °C[W/(m*K)] are the few other units in which Thermal Conductivity of Conduction can be measured.
