Thermal Resistivity and Conductivity

Thermal resistance is the ability of a material to resist flow of heat. Thermal resistivity is the reciprocal of thermal conductivity and can be expressed as

r = 1 / k                                (1)

where

r = thermal resistivity (moC/W, hr ft2 oF/(Btu in))

k = thermal conductivity (W/(moC), Btu in/(hr ft2 oF))

Thermal conductivity - k - is the property of a material indicating its ability to conduct heat.
