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 cal/g = 4186.8 joule per kilogram (J/kg)

2. Target SI Bridge (k_target):1 cal (th)/g = 4184 joule per kilogram (J/kg)

Step-by-step substitution for Calorie (IT)/gram → Calorie (th)/gram:V(cal (th)/g) = V(cal/g) × ( 4186.8 / 4184 ) = V(cal/g) × 1.000669

Mathematical FormulaValue in Calorie (th)/gram = Value in Calorie (IT)/gram × 1.00066922Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 50 Calorie (IT)/gram (cal/g) produces 50.033461 Calorie (th)/gram (cal (th)/g). In heavy-duty utility and industrial workloads, 10000 cal/g equals 10006.692161 cal (th)/g.

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