How to Convert Gram/centimeter/second to Pound-force second/sq. inch

Converting Gram/centimeter/second (g/(cm·s)) to Pound-force second/sq. inch (reyn) 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 Gram/centimeter/second equals 1.450377 × 10⁻⁵ Pound-force second/sq. inch, while 1 reyn equals 68947.57 g/(cm·s).

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 g/(cm·s) = 0.1 pascal second (Pa·s)

2. Target SI Bridge (k_target):1 reyn = 6894.757 pascal second (Pa·s)

Step-by-step substitution for Gram/centimeter/second → Pound-force second/sq. inch:V(reyn) = V(g/(cm·s)) × ( 0.1 / 6894.757 ) = V(g/(cm·s)) × 1.450377 × 10⁻⁵

Worked Example

Evaluating an input of 50 Gram/centimeter/second (g/(cm·s)) produces 0.000725189 Pound-force second/sq. inch (reyn). In heavy-duty utility and industrial workloads, 2500 g/(cm·s) equals 0.0362594 reyn.

Inverse check: 1 reyn = 68947.57 g/(cm·s).
