How to Convert Decipoise to Poundal second/sq. foot

Converting Decipoise (dP) to Poundal second/sq. foot (pdl·s/ft²) is a core calculation in Dynamic Viscosity, which quantifies a fluid's internal tangential resistance to shear deformation and laminar flow. This calculation bridges modern MKSA metric standards with the historical Gaussian centimetre-gram-second (CGS) electrostatic and electromagnetic framework. In CGS systems, electromagnetic units (such as statvolts, abvolts, dynes, ergs, and gauss) are formulated directly from mechanical dimensions, with electrostatic-to-electromagnetic relations tied to the speed of light in vacuum (c ≈ 2.99792458 × 10¹⁰ cm/s). Exactly 1 Decipoise translates to 0.00671969 Poundal second/sq. foot (1 pdl·s/ft² = 148.8164 dP).

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 dP = 0.01 pascal second (Pa·s)

2. Target SI Bridge (k_target):1 pdl·s/ft² = 1.488164 pascal second (Pa·s)

Step-by-step substitution for Decipoise → Poundal second/sq. foot:V(pdl·s/ft²) = V(dP) × ( 0.01 / 1.488164 ) = V(dP) × 0.00671969
