How to Convert CHU/hour/square foot to Calorie (IT)/hour/square centimeter
Converting CHU/hour/square foot (CHU/(h·ft²)) to Calorie (IT)/hour/square centimeter (cal/(h·cm²)) is a core calculation in Heat Flux Density, which measures the rate of thermal energy transfer radiating or conducting through a unit area per second. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 CHU/hour/square foot equals 0.488243 Calorie (IT)/hour/square centimeter, while 1 cal/(h·cm²) equals 2.04816 CHU/(h·ft²).
Mathematical Conversion Derivation via Coherent SI Base Unit
Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (watt per square meter (W/m²)) without arbitrary rounding:
1 CHU/(h·ft²) = 5.678269 watt per square meter (W/m²)1 cal/(h·cm²) = 11.630003 watt per square meter (W/m²)V(cal/(h·cm²)) = V(CHU/(h·ft²)) × ( 5.678269 / 11.630003 ) = V(CHU/(h·ft²)) × 0.488243Value in Calorie (IT)/hour/square centimeter = Value in CHU/hour/square foot × 0.48824314Direct computational formula applied for standard conversion.For an engineering input of 250 CHU/(h·ft²), applying the conversion factor yields exactly 122.060786 cal/(h·cm²). At larger operational scale, 10000 CHU/hour/square foot corresponds to 4882.431435 cal/(h·cm²).
Inverse check: 1 cal/(h·cm²) = 2.04816 CHU/(h·ft²).Understanding CHU/hour/square foot and Calorie (IT)/hour/square centimeter
