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 actus = 35.48 meter (m)

2. Target SI Bridge (k_target):1 nm = 1 × 10⁻⁹ meter (m)

Step-by-step substitution for Roman Actus → Nanometer:V(nm) = V(actus) × ( 35.48 / 1 × 10⁻⁹ ) = V(actus) × 3.548 × 10¹⁰

Mathematical FormulaValue in Nanometer = Value in Roman Actus × 3.548 × 10¹⁰Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Roman Actus (actus) to Nanometer (nm): multiply 50 by 3.548 × 10¹⁰ to get 1.774 × 10¹² nm. At an industrial engineering scale, 2500 actus converts to 8.87 × 10¹³ nm.

Inverse check: 1 nm = 2.818489 × 10⁻¹¹ actus.
