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:

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)

2. Target SI Bridge (ktarget):1 kJ/(kg·°C) = 1000 joule per kilogram kelvin (J/(kg·K))
Step-by-step substitution for Kilocalorie (IT)/kilogram/°C → Kilojoule/kilogram/°C:V(kJ/(kg·°C)) = V(kcal/(kg·°C)) × ( 4186.8 / 1000 ) = V(kcal/(kg·°C)) × 4.1868
