How to Convert Calorie (th)/minute/square centimeter to CHU/hour/square foot

Converting Calorie (th)/minute/square centimeter (cal (th)/(min·cm²)) to CHU/hour/square foot (CHU/(h·ft²)) 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 Calorie (th)/minute/square centimeter equals 122.807752 CHU/hour/square foot, while 1 CHU/(h·ft²) equals 0.00814281 cal (th)/(min·cm²).

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:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

1. Source SI Bridge (ksource):1 cal (th)/(min·cm²) = 697.335481 watt per square meter (W/m²)
2. Target SI Bridge (ktarget):1 CHU/(h·ft²) = 5.678269 watt per square meter (W/m²)
Step-by-step substitution for Calorie (th)/minute/square centimeter → CHU/hour/square foot:V(CHU/(h·ft²)) = V(cal (th)/(min·cm²)) × ( 697.335481 / 5.678269 ) = V(cal (th)/(min·cm²)) × 122.807752
