How to Convert Calorie (IT)/second/cm²/°C to CHU/hour/sq. foot/°C

Converting Calorie (IT)/second/cm²/°C (cal/(s·cm²·°C)) to CHU/hour/sq. foot/°C (CHU/(h·ft²·°C)) is a core calculation in Heat Transfer Coefficient, which quantifies the proportionality constant between the heat flux and the thermodynamic driving temperature difference. 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 (IT)/second/cm²/°C equals 7373.499084 CHU/hour/sq. foot/°C, while 1 CHU/(h·ft²·°C) equals 0.000135621 cal/(s·cm²·°C).

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 kelvin (W/(m²·K))) 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/(s·cm²·°C) = 41868 watt per square meter kelvin (W/(m²·K))
2. Target SI Bridge (ktarget):1 CHU/(h·ft²·°C) = 5.678173 watt per square meter kelvin (W/(m²·K))
Step-by-step substitution for Calorie (IT)/second/cm²/°C → CHU/hour/sq. foot/°C:V(CHU/(h·ft²·°C)) = V(cal/(s·cm²·°C)) × ( 41868 / 5.678173 ) = V(cal/(s·cm²·°C)) × 7373.499084
