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 (bit per second (bps)) 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 OC3 = 1.5552 × 10⁸ bit per second (bps)

2. Target SI Bridge (k_target):1 megabit/second = 1048576 bit per second (bps)

Step-by-step substitution for Oc3 → Megabit Per Second:V(megabit/second) = V(OC3) × ( 1.5552 × 10⁸ / 1048576 ) = V(OC3) × 148.31543
