Convert BTU per hour per foot per degree Fahrenheit to Kilowatt per metre degree Celsius

Convert BTU per hour per foot per degree Fahrenheit (BTU/(h·ft·°F)) to Kilowatt per metre degree Celsius (kW/(m·°C)) instantly and accurately.

From: BTU per hour per foot per degree Fahrenheit (BTU/(h·ft·°F))

To: Kilowatt per metre degree Celsius (kW/(m·°C))

Conversion Formula

kW/(m·°C) = BTU/(h·ft·°F) × 0.001730734666

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 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).
