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 cm = 0.01 meter (m)

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

Step-by-step substitution for Centimeter → Atomic Unit of Length (Bohr Radius):V(a₀) = V(cm) × ( 0.01 / 5.291772 × 10⁻¹¹ ) = V(cm) × 1.889726 × 10⁸

Worked Example

To convert 24 Centimeter (cm) to Atomic Unit of Length (Bohr Radius) (a₀): multiply 24 by 1.889726 × 10⁸ to get 4.535343 × 10⁹ a₀. At an industrial engineering scale, 2500 cm converts to 4.724315 × 10¹¹ a₀.

Inverse check: 1 a₀ = 5.291772 × 10⁻⁹ cm.
