Conversion Formula
lb/(ft·s) = Pa·s × 0.6719689751
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 foot-second
The pound per foot-second (lb/(ft·s)) equals 0.45359237/0.3048 ≈ 1.4882 Pa·s, the absolute viscosity unit in the foot-pound-second (FPS) system. It appears in legacy US chemical engineering textbooks and fluid mechanics problems stated in USC units. A heavy fuel oil at 50 °C with viscosity 0.050 Pa·s = 0.0336 lb/(ft·s). 1 lb/(ft·s) ≈ 1.4882 Pa·s = 14.882 P.
