Convert btu (th)/hour/sq. foot/°f to watt/square meter/k
Btu (th)/Hour/Sq. Foot/°F
The thermochemical British thermal unit per hour per square foot per degree Fahrenheit (Btu(th)/(h·ft²·°F)) uses the thermochemical BTU (1054.35 J). Slightly different from the IT version, it is applied in thermochemical research and precise calorimetric heat transfer calculations.
Watt/Square Meter/K
The watt per square metre per kelvin (W/(m²·K)) is the SI unit of heat transfer coefficient, also known as the U-value or film coefficient. It quantifies the rate of heat transfer per unit area per unit temperature difference. Typical values range from 2–25 W/(m²·K) for free convection to over 10,000 W/(m²·K) for boiling.
