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).
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).
