You can compute it using Fourier's law. It states that the rate of heat transfer through conduction is directly proportional to the thermal gradient (dT/dx). Mathematically,
q_x = - k * A * dT / dx (1D conduction)
where,
q_x - rate of heat transfer in x direction
k - thermal conductivity of the material
A - area normal to the direction of heat transfer
dT / dx - thermal gradient
The minus sign is necessary because heat is transferred in the direction of decreasing temperature.
Thermal conductivity is a transport property which indicates the rate at which energy is transferred through conduction. Efficient conductors have a high thermal conductivity. Materials with poor thermal conductivity are referred to as insulators.
