Conversion Formula
lb/(in·s) = Pa·s × 0.05599741459
About Pascal-seconds
The pascal-second (Pa·s) is the SI coherent unit of dynamic viscosity, equal to 1 kg/(m·s) = 1 N·s/m². Honey at 25 °C is ≈2-10 Pa·s; glycerol ≈1.4 Pa·s; bitumen 10⁴-10⁸ Pa·s. It replaced the poise in SI usage and is the standard unit in research and simulation software (CFD, process simulators). 1 Pa·s = 10 P = 1 000 cP.
About Pounds per inch-second
The pound per inch-second (lb/(in·s)) equals 0.45359237/0.0254 ≈ 17.858 Pa·s, used in plastics extrusion and rubber compounding industries where inch-based dimensions are combined with mass-based flow analysis. Polymer melt viscosities at processing temperatures are sometimes quoted in lb/(in·s) in older US extrusion equipment manuals. 1 lb/(in·s) ≈ 17.858 Pa·s = 12 lb/(ft·s).
