Convert Kilowatt per square metre kelvin to International table BTU per second per square foot per degree Fahrenheit
Convert Kilowatt per square metre kelvin (kW/(m²·K)) to International table BTU per second per square foot per degree Fahrenheit (BTU(IT)/(s·ft²·°F)) instantly and accurately.
Conversion Formula
BTU(IT)/(s·ft²·°F) = kW/(m²·K) × 0.04891949547
About Kilowatt per square metre kelvin
The kilowatt per square metre kelvin (kW/(m²·K)) equals exactly 1000 W/(m²·K). Characteristic of high-performance industrial applications: nucleate pool boiling of water reaches 5-50 kW/(m²·K), compact plate heat exchangers with liquid-liquid flow achieve 3-8 kW/(m²·K), and jet impingement cooling on metal surfaces can exceed 10 kW/(m²·K). 1 kW/(m²·K) = 10³ W/(m²·K).
About International table BTU per second per square foot per degree Fahrenheit
The international table BTU per second per square foot per degree Fahrenheit (BTU(IT)/(s·ft²·°F)) equals ≈ 20442 W/(m²·K) (= 3600 × BTU(IT)/(h·ft²·°F)). Encountered in atmospheric re-entry aerodynamic heating analysis, solid rocket motor nozzle throat design, and nuclear reactor thermal-hydraulics with peak surface heat transfer rates. 1 BTU(IT)/(s·ft²·°F) ≈ 20442 W/(m²·K).
