The unit of thermal conductivity is?

The unit of thermal conductivity is? Correct Answer W/mK

From the Fourier law of heat transfer,

⇒ Fourier law of heat conduction states that rate of heat flux is directly proportional to temperature gradient.

⇒ Q = - kA (dT/dx)

Where k is thermal conductivity (W/mK)

A is the area of the flow m2

dT/dx is the temperature gradient
