Convert watt/square meter/k to chu/hour/sq. foot/°c
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.
CHU/Hour/Sq. Foot/°C
The Celsius Heat Unit per hour per square foot per degree Celsius (CHU/(h·ft²·°C)) is a hybrid imperial-Celsius unit of heat transfer coefficient equal to approximately 5.678 W/(m²·K). It was used in older British engineering standards and handbooks as a bridge between metric temperature and imperial area units.
