Transfer of heat within thermally conductive body or between thermally contacted bodies due to temperature difference is known as Conductive Heat Transfer. You can use this calculator to calculate conductive heat transfer in solid bodies. For more details, we suggest you to read this article on Conduction Heat Transfer.
Conductive heat Transfer Formula
Conductive Heat transfer (Qc) = – K A dT/L
Qc = Conductive heat transfer per unit time in watt
A = cross section area in square meter
k = Material Thermal Conductivity (W/mK)
dT = Temperature Differential
L = Thickness/Length of the part in Meter
