Thermal conductivity is defined as the property of any material to conduct heat. Heat transfer takes place at a lower rate in all the materials of low thermal conductivity. Materials having thermal conductivity are greatly used in heat sink applications and materials having low thermal conductivity are used as thermal insulation. A thermal conductivity of a material depends on the temperature, and its reciprocal is known as thermal resistivity.
The SI unit of thermal conductivity is watts per meter-Kelvin and its variables are Mass, Length, Time, and temperature. In the Imperial unit, thermal conductivity is measured in BTU.
