Convert Celsius Heat Unit per hour per square foot (CHU/(h·ft²)) to International table calorie per second per square centimetre (cal(IT)/(s·cm²)) instantly and accurately.
Conversion Formula
cal(IT)/(s·cm²) = CHU/(h·ft²) × 0.0001356229899
About Celsius Heat Unit per hour per square foot
The Celsius heat unit per hour per square foot (CHU/(h·ft²)) equals (9/5)×1055.05585262/(3600×0.09290304) ≈ 5.6783 W/m². The CHU (= 9/5 BTU(IT)) uses a 1 °C temperature interval instead of 1 °F; historically used in UK and Canadian heating engineering. 1 CHU/(h·ft²) ≈ 5.6783 W/m² = (9/5) × BTU(IT)/(h·ft²).
About International table calorie per second per square centimetre
The international table calorie per second per square centimetre (cal(IT)/(s·cm²)) equals exactly 41868 W/m² (1 cal(IT) = 4.1868 J; 1 cm² = 10⁻⁴ m²). The IT variant of the high-flux CGS unit, slightly larger than the thermochemical counterpart due to the IT calorie definition. 1 cal(IT)/(s·cm²) = 41868 W/m².
