Convert btu (it) foot/hour/sq. foot/°f to watt/meter/k
Btu (IT) Foot/Hour/Sq. Foot/°F
The British thermal unit foot per hour per square foot per degree Fahrenheit (Btu·ft/(h·ft²·°F)) is the standard imperial unit of thermal conductivity in North America. It equals approximately 1.7307 W/(m·K). Used in US building codes, insulation ratings, and mechanical engineering standards.
Watt/Meter/K
The watt per metre per kelvin (W/(m·K)) is the SI unit of thermal conductivity. It represents the rate of heat transfer through a material of unit thickness per unit area per unit temperature gradient. Copper has a value of ~400 W/(m·K) while insulation materials have values below 0.1 W/(m·K).
