Question

what is the diamension of thermal resistance ?

Answer 1

Thermal resistance is a measurement of a temperature difference by which an object or material resists a heat flow (heat per time unit or thermal resistance). Thermal resistance is the reciprocal of thermal conductance.
Units in which thermal resistance R is measured: (m²K)/W
where
W=J/s stands for Watt in which heat flow is measured;
m^2-square meters, measuring area;
K-Kelvin, measuring temperature.
