It represents the quantity of energy transfered by surface unit and time unit , under a temperature gradient.
It is the opposite of the electrical resistivity. It corresponds to the "conductance" of a material of 1 meter length and 1m² section.
The "conductance" is the opposite of the resistivity ; Its unit is the " Siemens " : G = 1/R
Electrical conductivity in 10 (7) S/m (siemens/m) / thermal conductivity in W/m.k
