Fourier's Law of Heat Conduction
Formula
Q = k × A × (ΔT / L)
Rearranged:
k = Q × L / (A × ΔT)
Where:
- • k = thermal conductivity (W/m·K)
- • Q = heat transfer rate (W)
- • A = cross-sectional area (m²)
- • ΔT = temperature difference (K)
- • L = thickness (m)

- • Copper: 401 W/m·K
- • Aluminum: 237 W/m·K
- • Steel: 50 W/m·K
- • Water: 0.6 W/m·K
- • Air: 0.024 W/m·K
