How to Convert Kilocalorie (IT)/hour/ft²/°C to Calorie (IT)/second/cm²/°C

Converting Kilocalorie (IT)/hour/ft²/°C (kcal/(h·ft²·°C)) to Calorie (IT)/second/cm²/°C (cal/(s·cm²·°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 Kilocalorie (IT)/hour/ft²/°C equals 0.000298984 Calorie (IT)/second/cm²/°C, while 1 cal/(s·cm²·°C) equals 3344.658674 kcal/(h·ft²·°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)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 kcal/(h·ft²·°C) = 12.517869 watt per square meter kelvin (W/(m²·K))
2. Target SI Bridge (ktarget):1 cal/(s·cm²·°C) = 41868 watt per square meter kelvin (W/(m²·K))
Step-by-step substitution for Kilocalorie (IT)/hour/ft²/°C → Calorie (IT)/second/cm²/°C:V(cal/(s·cm²·°C)) = V(kcal/(h·ft²·°C)) × ( 12.517869 / 41868 ) = V(kcal/(h·ft²·°C)) × 0.000298984
