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 (watt (W)) 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 GW = 1 × 10⁹ watt (W)

2. Target SI Bridge (k_target):1 kcal/s = 4186.8 watt (W)

Step-by-step substitution for Gigawatt → Kilocalorie (IT)/second:V(kcal/s) = V(GW) × ( 1 × 10⁹ / 4186.8 ) = V(GW) × 238845.896627
