How to Convert Dekapoise to Slug/foot/second

Converting Dekapoise (daP) to Slug/foot/second (slug/(ft·s)) 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 Dekapoise translates to 0.0208854 Slug/foot/second (1 slug/(ft·s) = 47.88026 daP).

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 daP = 1 pascal second (Pa·s)

2. Target SI Bridge (k_target):1 slug/(ft·s) = 47.88026 pascal second (Pa·s)

Step-by-step substitution for Dekapoise → Slug/foot/second:V(slug/(ft·s)) = V(daP) × ( 1 / 47.88026 ) = V(daP) × 0.0208854

Mathematical FormulaValue in Slug/foot/second = Value in Dekapoise × 0.020885434Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Dekapoise (daP) to Slug/foot/second (slug/(ft·s)): multiply 120 by 0.0208854 to get 2.506252 slug/(ft·s). At an industrial engineering scale, 2500 daP converts to 52.213584 slug/(ft·s).

Inverse check: 1 slug/(ft·s) = 47.88026 daP.
