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 Poises

The poise (P) equals 0.1 Pa·s (exact), defined in the CGS system as 1 g/(cm·s). Named after Jean Louis Marie Poiseuille, it was the dominant viscosity unit before SI adoption. Fluid-mechanics textbooks and older ASTM and API data tables still list viscosities in P. Motor oil at 100 °C is ≈0.02-0.05 P; water at 20 °C is ≈0.01 P (= 1 cP). 1 P = 0.1 Pa·s = 100 cP.
