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 (joule per kilogram kelvin (J/(kg·K))) without arbitrary rounding:

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 (k_source):1 kcal/(kg·°C) = 4184.000002 joule per kilogram kelvin (J/(kg·K))

2. Target SI Bridge (k_target):1 kJ/(kg·K) = 1000 joule per kilogram kelvin (J/(kg·K))

Step-by-step substitution for Kilocalorie/kilogram celsius → Kilojoule/kilogram kelvin:V(kJ/(kg·K)) = V(kcal/(kg·°C)) × ( 4184.000002 / 1000 ) = V(kcal/(kg·°C)) × 4.184
