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 (meter (m)) 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 Gm = 1 × 10⁹ meter (m)

2. Target SI Bridge (k_target):1 a₀ = 5.291772 × 10⁻¹¹ meter (m)

Step-by-step substitution for Gigameter → Atomic Unit of Length (Bohr Radius):V(a₀) = V(Gm) × ( 1 × 10⁹ / 5.291772 × 10⁻¹¹ ) = V(Gm) × 1.889726 × 10¹⁹
