Heat Transfer Calculator

Calculate heat flow via conduction, convection, and radiation.

Conduction Parameters
Fourier's Law of Heat Conduction.
Heat Flow Rate (Q)
Calculated power transfer.
40000.00 W
Formula
Q = k · A · (T₁ - T₂) / L

Important Note on Units

For radiation calculations, temperatures must be in Kelvin (K). For conduction and convection, the temperature difference (ΔT) is the same in Celsius (°C) and Kelvin (K), so either can be used as long as they are consistent.
