How to Convert Pound/foot/second to Dyne second/sq. centimeter

Converting Pound/foot/second (lb/(ft·s)) to Dyne second/sq. centimeter (dyn·s/cm²) 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 Pound/foot/second translates to 14.881639 Dyne second/sq. centimeter (1 dyn·s/cm² = 0.0671969 lb/(ft·s)).

Direct Factor1 lb/(ft·s) = 14.881639 dyn·s/cm²

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 lb/(ft·s) = 1.488164 pascal second (Pa·s)

2. Target SI Bridge (k_target):1 dyn·s/cm² = 0.1 pascal second (Pa·s)

Step-by-step substitution for Pound/foot/second → Dyne second/sq. centimeter:V(dyn·s/cm²) = V(lb/(ft·s)) × ( 1.488164 / 0.1 ) = V(lb/(ft·s)) × 14.881639

Worked Example

Converting 15 lb/(ft·s) yields an exact output of 223.224592 dyn·s/cm² in Dyne second/sq. centimeter. Under higher industrial throughput, 1000 lb/(ft·s) translates to 14881.639436 dyn·s/cm².
