How to Convert Slug/foot/second to Poise

Converting Slug/foot/second (slug/(ft·s)) to Poise (P) 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 Slug/foot/second translates to 478.80259 Poise (1 P = 0.00208854 slug/(ft·s)).

2. Target SI Bridge (k_target):1 P = 0.1 pascal second (Pa·s)

Step-by-step substitution for Slug/foot/second → Poise:V(P) = V(slug/(ft·s)) × ( 47.880259 / 0.1 ) = V(slug/(ft·s)) × 478.80259

Mathematical FormulaValue in Poise = Value in Slug/foot/second × 478.8025898Direct computational formula applied for standard conversion.

Worked Example
