How to Convert Pound/foot/hour to Gram/centimeter/second

Converting Pound/foot/hour (lb/(ft·h)) to Gram/centimeter/second (g/(cm·s)) is a core calculation in Dynamic Viscosity, which quantifies a fluid's internal tangential resistance to shear deformation and laminar flow. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Pound/foot/hour equals 0.00413379 Gram/centimeter/second, while 1 g/(cm·s) equals 241.908831 lb/(ft·h).

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·h) = 0.000413379 pascal second (Pa·s)

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

Step-by-step substitution for Pound/foot/hour → Gram/centimeter/second:V(g/(cm·s)) = V(lb/(ft·h)) × ( 0.000413379 / 0.1 ) = V(lb/(ft·h)) × 0.00413379

Worked Example

For an engineering input of 15 lb/(ft·h), applying the conversion factor yields exactly 0.0620068 g/(cm·s). At larger operational scale, 240 Pound/foot/hour corresponds to 0.992109 g/(cm·s).

Inverse check: 1 g/(cm·s) = 241.908831 lb/(ft·h).
