Conversion Formula
cal(IT)/(s·cm²·°C) = CHU/(h·ft²·°C) × 0.0001356229899
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 International table calorie per second per square centimetre per degree Celsius
The international table calorie per second per square centimetre per degree Celsius (cal(IT)/(s·cm²·°C)) equals exactly 41868 W/(m²·K) (1 cal(IT) = 4.1868 J; 1 cm² = 10⁻⁴ m²; 1 °C = 1 K). Slightly larger than the thermochemical variant; used in IT-based thermophysical property tables for extreme thermal environments such as nuclear and fusion reactor surfaces. 1 cal(IT)/(s·cm²·°C) = 41868 W/(m²·K).
