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 (second (s)) 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 kyr = 3.15576 × 10¹⁰ second (s)
2. Target SI Bridge (ktarget):1 Quindecennial = 4.73364 × 10⁸ second (s)
Step-by-step substitution for Millennium → Quindecennial:V(Quindecennial) = V(kyr) × ( 3.15576 × 10¹⁰ / 4.73364 × 10⁸ ) = V(kyr) × 66.666667
Mathematical FormulaValue in Quindecennial = Value in Millennium × 66.66666667Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 15 kyr, applying the conversion factor yields exactly 1000 Quindecennial. At larger operational scale, 5000 Millennium corresponds to 333333.333333 Quindecennial.

Inverse check: 1 Quindecennial = 0.015 kyr.
