How to Convert Hectopoise to Pound/foot/hour

Converting Hectopoise (hP) 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 Hectopoise translates to 24190.883105 Pound/foot/hour (1 lb/(ft·h) = 4.133789 × 10⁻⁵ hP).

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 hP = 10 pascal second (Pa·s)

2. Target SI Bridge (k_target):1 lb/(ft·h) = 0.000413379 pascal second (Pa·s)

Step-by-step substitution for Hectopoise → Pound/foot/hour:V(lb/(ft·h)) = V(hP) × ( 10 / 0.000413379 ) = V(hP) × 24190.883105

Worked Example

Converting 36 hP yields an exact output of 870871.791781 lb/(ft·h) in Pound/foot/hour. Under higher industrial throughput, 2500 hP translates to 6.047721 × 10⁷ lb/(ft·h).

Inverse check: 1 lb/(ft·h) = 4.133789 × 10⁻⁵ hP.
