Conversion Formula
CHU/(h·ft²·°C) = cal(th)/(h·cm²·°C) × 2.04679169
About Thermochemical calorie per hour per square centimetre per degree Celsius
The thermochemical calorie per hour per square centimetre per degree Celsius (cal(th)/(h·cm²·°C)) equals 4.184/0.36 ≈ 11.622 W/(m²·K) (1 cal(th) = 4.184 J; 1 cm² = 10⁻⁴ m²). A CGS-derived unit found in older heat transfer textbooks and chemical engineering publications, especially in Eastern European and Japanese technical literature. 1 cal(th)/(h·cm²·°C) ≈ 11.622 W/(m²·K).
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).
