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 (square meter (m²)) 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 circ mil = 5.067075 × 10⁻¹⁰ square meter (m²)

2. Target SI Bridge (k_target):1 µm² = 1 × 10⁻¹² square meter (m²)

Step-by-step substitution for Circular Mil → Square Micrometer:V(µm²) = V(circ mil) × ( 5.067075 × 10⁻¹⁰ / 1 × 10⁻¹² ) = V(circ mil) × 506.707479
