Convert BTU per hour per foot per degree Fahrenheit to Milliwatt per centimetre kelvin
Convert BTU per hour per foot per degree Fahrenheit (BTU/(h·ft·°F)) to Milliwatt per centimetre kelvin (mW/(cm·K)) instantly and accurately.
Conversion Formula
mW/(cm·K) = BTU/(h·ft·°F) × 17.30734666
About BTU per hour per foot per degree Fahrenheit
The BTU/(h·ft·°F) equals (1055.05585262 × 9)/(3600 × 0.3048 × 5) W/(m·K) ≈1.7307 W/(m·K). Standard US thermal conductivity unit in ASHRAE Handbook and ASTM C1045. Copper: ≈223; carbon steel: ≈26; brick: ≈0.44; glass fibre insulation: ≈0.025 BTU/(h·ft·°F). 1 BTU/(h·ft·°F) = 12 BTU·in/(h·ft²·°F) ≈1.7307 W/(m·K).
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).
