How to Convert Poundal second/sq. foot to Newton second/square meter

Converting Poundal second/sq. foot (pdl·s/ft²) to Newton second/square meter (N·s/m²) is a core calculation in Dynamic Viscosity, which quantifies a fluid's internal tangential resistance to shear deformation and laminar flow. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Poundal second/sq. foot equals 1.488164 Newton second/square meter, while 1 N·s/m² equals 0.671969 pdl·s/ft².

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 N·s/m² = 1 pascal second (Pa·s)

Step-by-step substitution for Poundal second/sq. foot → Newton second/square meter:V(N·s/m²) = V(pdl·s/ft²) × ( 1.488164 / 1 ) = V(pdl·s/ft²) × 1.488164
