About Kilowatt per metre degree Celsius

The kilowatt per metre degree Celsius (kW/(m·°C)) equals exactly 1 kW/(m·K) = 1000 W/(m·K) since temperature intervals 1 °C = 1 K. An alternative notation for kW/(m·K) used in European engineering and scientific literature. Type IIa diamond ≈2.2 kW/(m·°C); crystalline silicon ≈0.14 kW/(m·°C); ²⁸Si single crystal ≈1.0 kW/(m·°C). 1 kW/(m·°C) = 1 kW/(m·K) = 1000 W/(m·K).

About BTU inch per hour per square foot per degree Fahrenheit

The BTU·in/(h·ft²·°F) equals (1055.05585262 × 0.0254 × 9)/(3600 × 0.09290304 × 5) W/(m·K) ≈0.1442 W/(m·K). The standard US k-factor unit for insulation per ASTM C177, C335, and C518. Mineral wool ≈0.25; expanded polystyrene ≈0.24; polyurethane foam ≈0.14 BTU·in/(h·ft²·°F). 1 BTU·in/(h·ft²·°F) ≈0.1442 W/(m·K).
