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 (coulomb (C)) 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 A·s = 1 coulomb (C)

2. Target SI Bridge (k_target):1 e = 1.602177 × 10⁻¹⁹ coulomb (C)

Step-by-step substitution for Ampere-second → Elementary charge:V(e) = V(A·s) × ( 1 / 1.602177 × 10⁻¹⁹ ) = V(A·s) × 6.241509 × 10¹⁸
