Convert International table BTU per hour per square inch per degree Fahrenheit to Watt per square centimetre kelvin
Convert International table BTU per hour per square inch per degree Fahrenheit (BTU(IT)/(h·in²·°F)) to Watt per square centimetre kelvin (W/(cm²·K)) instantly and accurately.
Conversion Formula
W/(cm²·K) = BTU(IT)/(h·in²·°F) × 0.08176699211
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).
About Watt per square centimetre kelvin
The watt per square centimetre kelvin (W/(cm²·K)) equals exactly 10⁴ W/(m²·K). Relevant for extreme cooling: nuclear reactor fuel rod cladding surfaces reach up to 5 W/(cm²·K), spray cooling and microjet impingement in power electronics reach 1-10 W/(cm²·K), and condensation of refrigerants can approach 1 W/(cm²·K). 1 W/(cm²·K) = 10⁴ W/(m²·K) = 10 kW/(m²·K).
