How to Convert Kilocalorie (IT)/hour/ft²/°C to Kilocalorie (IT)/hour/m²/°C

Converting Kilocalorie (IT)/hour/ft²/°C (kcal/(h·ft²·°C)) to Kilocalorie (IT)/hour/m²/°C (kcal/(h·m²·°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 10.76343 Kilocalorie (IT)/hour/m²/°C, while 1 kcal/(h·m²·°C) equals 0.0929072 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)

2. Target SI Bridge (ktarget):1 kcal/(h·m²·°C) = 1.163 watt per square meter kelvin (W/(m²·K))
Step-by-step substitution for Kilocalorie (IT)/hour/ft²/°C → Kilocalorie (IT)/hour/m²/°C:V(kcal/(h·m²·°C)) = V(kcal/(h·ft²·°C)) × ( 12.517869 / 1.163 ) = V(kcal/(h·ft²·°C)) × 10.76343
