How to Convert Poundal second/sq. foot to Kilopoise

Converting Poundal second/sq. foot (pdl·s/ft²) to Kilopoise (kP) 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 Poundal second/sq. foot translates to 0.0148816 Kilopoise (1 kP = 67.196895 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 kP = 100 pascal second (Pa·s)

Step-by-step substitution for Poundal second/sq. foot → Kilopoise:V(kP) = V(pdl·s/ft²) × ( 1.488164 / 100 ) = V(pdl·s/ft²) × 0.0148816

Mathematical FormulaValue in Kilopoise = Value in Poundal second/sq. foot × 0.01488164Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Poundal second/sq. foot (pdl·s/ft²) to Kilopoise (kP): multiply 120 by 0.0148816 to get 1.785797 kP. At an industrial engineering scale, 480 pdl·s/ft² converts to 7.143187 kP.

Inverse check: 1 kP = 67.196895 pdl·s/ft².
