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 kW = 1000 watt (W)

2. Target SI Bridge (k_target):1 cal/s = 4.1868 watt (W)

Step-by-step substitution for Kilowatt → Calorie (IT)/second:V(cal/s) = V(kW) × ( 1000 / 4.1868 ) = V(kW) × 238.845897
