About Megawatt per metre kelvin
The megawatt per metre kelvin (MW/(m·K)) equals exactly 10⁶ W/(m·K). A theoretical and research unit for modelling exotic or nanostructured materials: theoretical carbon nanotube axial conductivity predictions and astrophysical plasma heat transport can reach the MW/(m·K) range. No bulk engineering material approaches this value. 1 MW/(m·K) = 10⁶ W/(m·K) = 1000 kW/(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).
