Thermal resistanceUnits Type ⤴

Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Thermal resistance is the reciprocal of thermal conductance. (Absolute) thermal resistance R in K/W is a property of a particular component. For example, a characteristic of a heat sink. Specific thermal resistance or specific thermal resistivity R? in (K·m)/W is a material constant.
