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 R⊕(eq) = 6378136.767662 meter (m)

2. Target SI Bridge (k_target):1 am = 1 × 10⁻¹⁸ meter (m)

Step-by-step substitution for Earth's Equatorial Radius → Attometer:V(am) = V(R⊕(eq)) × ( 6378136.767662 / 1 × 10⁻¹⁸ ) = V(R⊕(eq)) × 6.378137 × 10²⁴
