Conversion Formula
W/(cm²·K) = CHU/(h·ft²·°C) × 0.0005678263341
About Celsius Heat Unit per hour per square foot per degree Celsius
The Celsius heat unit per hour per square foot per degree Celsius (CHU/(h·ft²·°C)) equals ≈ 5.6783 W/(m²·K) - numerically identical to BTU(IT)/(h·ft²·°F). Used in UK and Canadian steam and process engineering; the temperature-interval ratio °F/°C = 5/9 is exactly compensated by the energy ratio CHU/BTU(IT) = 9/5, making both units numerically equal. 1 CHU/(h·ft²·°C) = 1 BTU(IT)/(h·ft²·°F) ≈ 5.6783 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).
