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 actus = 35.48 meter (m)

Step-by-step substitution for Gigameter → Roman Actus:V(actus) = V(Gm) × ( 1 × 10⁹ / 35.48 ) = V(Gm) × 2.818489 × 10⁷

Mathematical FormulaValue in Roman Actus = Value in Gigameter × 2.81848929 × 10⁷Direct computational formula applied for standard conversion.

Worked Example

Converting 250 Gm yields an exact output of 7.046223 × 10⁹ actus in Roman Actus. Under higher industrial throughput, 100 Gm translates to 2.818489 × 10⁹ actus.

Inverse check: 1 actus = 3.548 × 10⁻⁸ Gm.
