Heat Conduction Calculator (Fourier’s Law)

Estimate steady-state heat transfer through a flat layer: Q̇ = k·A·ΔT/L. Optional: energy over time.

Typical approximate values; real k varies by temperature and alloy.
Higher k = better heat conductor.
Surface area the heat flows through.
ΔT size is the same in °C and K.
Layer thickness (must be > 0).
hours
If provided, energy = Q̇ × time (kWh).
Q̇ = k · A · ΔT / L
Heat flux: q″ = Q̇ / A
Energy: E = Q̇ · t
Steady-state, 1D, no convection/radiation included.
