I have been working on selecting thermal pads recently and have found that thermal pads can be specified either with a thermal conductivity (W/mK) or thermal resistance. The thermal resistance often comes with the units, Km[sup]2[/sup]/W.
I have often been told that this means thermal resistance per unit area. However, looking at the units, since m[sup]2[/sup] is on the numerator, this does not seem to be the case. Also, a bigger area should mean less total resistance.
I have often struggled with wrapping my head around this. What is the correct way of understanding the units Km[sup]2[/sup]/W?
