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 (pascal second (Pa·s)) 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 pdl·s/ft² = 1.488164 pascal second (Pa·s)

2. Target SI Bridge (k_target):1 mN·s/m² = 0.001 pascal second (Pa·s)

Step-by-step substitution for Poundal second/sq. foot → Millinewton second/sq. meter:V(mN·s/m²) = V(pdl·s/ft²) × ( 1.488164 / 0.001 ) = V(pdl·s/ft²) × 1488.164
