Convert Kilowatt per square metre kelvin to International table BTU per hour per square inch per degree Fahrenheit
Convert Kilowatt per square metre kelvin (kW/(m²·K)) to International table BTU per hour per square inch per degree Fahrenheit (BTU(IT)/(h·in²·°F)) instantly and accurately.
Conversion Formula
BTU(IT)/(h·in²·°F) = kW/(m²·K) × 1.222987387
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 hour per square inch per degree Fahrenheit
The international table BTU per hour per square inch per degree Fahrenheit (BTU(IT)/(h·in²·°F)) equals ≈ 817.67 W/(m²·K) (1 in² = 6.4516×10⁻⁴ m²; 1 °F = 5/9 K). Encountered in US electronics thermal management, semiconductor package datasheets, and heat sink characterisation where contact areas are measured in square inches. 1 BTU(IT)/(h·in²·°F) ≈ 817.67 W/(m²·K).
