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)
1. Source SI Bridge (ksource):1 cal/(g·°C) = 4186.8 joule per kilogram kelvin (J/(kg·K))
2. Target SI Bridge (ktarget):1 J/(kg·K) = 1 joule per kilogram kelvin (J/(kg·K))
Step-by-step substitution for Calorie (IT)/gram/°C → Joule/kilogram/K:V(J/(kg·K)) = V(cal/(g·°C)) × ( 4186.8 / 1 ) = V(cal/(g·°C)) × 4186.8
Mathematical FormulaValue in Joule/kilogram/K = Value in Calorie (IT)/gram/°C × 4186.8Direct computational formula applied for standard conversion.
Worked Example

To convert 50 Calorie (IT)/gram/°C (cal/(g·°C)) to Joule/kilogram/K (J/(kg·K)): multiply 50 by 4186.8 to get 209340 J/(kg·K). At an industrial engineering scale, 240 cal/(g·°C) converts to 1004832 J/(kg·K).
