Conversion Formula
BTU·in/(h·ft²·°F) = mW/(cm·K) × 0.6933471799
About Milliwatt per centimetre kelvin
The milliwatt per centimetre kelvin (mW/(cm·K)) equals exactly 0.1 W/(m·K). Used in semiconductor and thermoelectric materials research: bismuth telluride ≈15 mW/(cm·K), yttria-stabilised zirconia ≈2 mW/(cm·K). Bridges the scale gap between mW/(m·K) for insulators and W/(m·K) for bulk solids. 1 mW/(cm·K) = 0.1 W/(m·K) = 100 mW/(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).
