Convert BTU per hour per foot per degree Fahrenheit to Watt per centimetre kelvin

Convert BTU per hour per foot per degree Fahrenheit (BTU/(h·ft·°F)) to Watt per centimetre kelvin (W/(cm·K)) instantly and accurately.

BTU per hour per foot per degree Fahrenheit (BTU/(h·ft·°F))
Watt per centimetre kelvin (W/(cm·K))

Conversion Formula

W/(cm·K) = BTU/(h·ft·°F) × 0.01730734666

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 Watt per centimetre kelvin

The watt per centimetre kelvin (W/(cm·K)) equals exactly 100 W/(m·K). Used for highly conductive materials in electronics and cryogenics: silver ≈4.29, copper ≈3.85, aluminium ≈2.05 W/(cm·K); synthetic diamond ≈22 W/(cm·K). Common in semiconductor and power device literature where component dimensions are centimetre-scale. 1 W/(cm·K) = 100 W/(m·K).
