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.
About Centipoises
The centipoise (cP) equals 10⁻³ Pa·s, numerically equal to 1 mPa·s. It remains the most widely used practical unit in industry because water at 20 °C has a viscosity of almost exactly 1 cP. Process engineers, petroleum analysts, and food technologists all specify viscosity in cP. Motor oil SAE 10W has a cold-viscosity limit of ≈3 500 cP at -25 °C. 1 cP = 10⁻³ Pa·s = 10⁻² P.
