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 (J/kg)) 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 = 4186.798188 joule per kilogram (J/kg)

2. Target SI Bridge (k_target):1 cal (th)/g = 4183.995381 joule per kilogram (J/kg)

Step-by-step substitution for Kilocalorie (IT)/kilogram → Calorie (th)/gram:V(cal (th)/g) = V(kcal/kg) × ( 4186.798188 / 4183.995381 ) = V(kcal/kg) × 1.00067

Mathematical FormulaValue in Calorie (th)/gram = Value in Kilocalorie (IT)/kilogram × 1.00066989Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Kilocalorie (IT)/kilogram (kcal/kg) to Calorie (th)/gram (cal (th)/g): multiply 50 by 1.00067 to get 50.033494 cal (th)/g. At an industrial engineering scale, 240 kcal/kg converts to 240.160773 cal (th)/g.

Inverse check: 1 cal (th)/g = 0.999331 kcal/kg.
