How to Convert Poise to Pound/foot/hour

Converting Poise (P) to Pound/foot/hour (lb/(ft·h)) 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 Poise translates to 241.908831 Pound/foot/hour (1 lb/(ft·h) = 0.00413379 P).

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:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 P = 0.1 pascal second (Pa·s)
2. Target SI Bridge (ktarget):1 lb/(ft·h) = 0.000413379 pascal second (Pa·s)
Step-by-step substitution for Poise → Pound/foot/hour:V(lb/(ft·h)) = V(P) × ( 0.1 / 0.000413379 ) = V(P) × 241.908831

Worked Example

Converting 8 P yields an exact output of 1935.270648 lb/(ft·h) in Pound/foot/hour. Under higher industrial throughput, 10000 P translates to 2419088.310502 lb/(ft·h).

Inverse check: 1 lb/(ft·h) = 0.00413379 P.
