Thermal conductance
= Thermal conductance
{title2=$G=1/R_{\rm th}$}
<Thermal conductance> is the <heat transfer> rate divided by the driving <temperature> difference in a linear contact model. It is the reciprocal of <thermal resistance>, with units $\mathrm{W\,K^{-1}}$; thus $\dot Q=G(T_1-T_2)$ for <heat> transferred from body 1 to body 2.
