Convert btu (it)/hour/sq. foot/°f to btu (it)/second/sq. foot/°f
Btu (IT)/Hour/Sq. Foot/°F
The British thermal unit per hour per square foot per degree Fahrenheit (Btu/(h·ft²·°F)) equals approximately 5.678 W/(m²·K). It is the standard imperial unit for heat transfer coefficient (U-value) in North American HVAC, building codes, and heat exchanger design and is related to the R-value of insulation.
Btu (IT)/Second/Sq. Foot/°F
The British thermal unit per second per square foot per degree Fahrenheit (Btu/(s·ft²·°F)) equals approximately 20,442 W/(m²·K). This high-rate imperial unit is used for intense heat transfer situations such as condensation, boiling, and rocket nozzle cooling in North American engineering.
