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 Tm = 1 × 10¹² meter (m)

2. Target SI Bridge (k_target):1 actus = 35.48 meter (m)

Step-by-step substitution for Terameter → Roman Actus:V(actus) = V(Tm) × ( 1 × 10¹² / 35.48 ) = V(Tm) × 2.818489 × 10¹⁰

Mathematical FormulaValue in Roman Actus = Value in Terameter × 2.81848929 × 10¹⁰Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 120 Terameter (Tm) produces 3.382187 × 10¹² Roman Actus (actus). In heavy-duty utility and industrial workloads, 10000 Tm equals 2.818489 × 10¹⁴ actus.

Inverse check: 1 actus = 3.548 × 10⁻¹¹ Tm.
