Common Thermal Conductivity Conversions
- 1 W/(m·K) = 1 W/(m·°C) (exact: 1 K = 1 °C for temperature intervals)
- 1 BTU/(h·ft·°F) ≈ 1.7307 W/(m·K); 1 W/(m·K) ≈ 0.5779 BTU/(h·ft·°F)
- 1 BTU·in/(h·ft²·°F) ≈ 0.1442 W/(m·K); 12 BTU·in/(h·ft²·°F) = 1 BTU/(h·ft·°F)
- 1 kcal/(m·h·°C) = 1.163 W/(m·K) (exact, given 1 kcal(IT) = 4186.8 J)
- 1 W/(cm·K) = 100 W/(m·K); 1 mW/(cm·K) = 0.1 W/(m·K); 1 mW/(m·K) = 10-3 W/(m·K)
- 1 cal(th)/(cm·s·°C) = 418.4 W/(m·K); 1 cal(IT)/(cm·s·°C) = 418.68 W/(m·K)
- 1 kW/(m·K) = 1000 W/(m·K) = 10 W/(cm·K)
- Air ≈ 0.026 W/(m·K); expanded polystyrene ≈ 0.033 W/(m·K); glass ≈ 1.0 W/(m·K)
- Stainless steel ≈ 15 W/(m·K); aluminium ≈ 205 W/(m·K); copper ≈ 385 W/(m·K); diamond ≈ 2200 W/(m·K)
