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