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 (radian (rad)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 rad = 57.29578 radian (rad)
2. Target SI Bridge (ktarget):1 MOA = 0.0166667 radian (rad)
Step-by-step substitution for Radian → Minute of arc:V(MOA) = V(rad) × ( 57.29578 / 0.0166667 ) = V(rad) × 3437.746771
Mathematical FormulaValue in Minute of arc = Value in Radian × 3437.74677078Direct computational formula applied for standard conversion.
