**Definition:** The SI unit of thermal resistance. It measures the opposition to the heat movement in a material or system. It is measured in units of degrees Kelvin per watt (K/W) and indicates how much temperature difference is required to transfer a unit of heat current through a material or object.

**Synonyms:** - Degree Kelvin per Watt - K/W - K/W - K/W - Kelvin / Watt
