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 Pound-force seconds per square foot
The pound-force second per square foot (lbf·s/ft²) equals (9.80665 × 0.45359237) / 0.3048² ≈ 47.880 Pa·s, numerically identical to slug/(ft·s). It appears in US civil and structural engineering fluid mechanics, pump hydraulics texts, and older API pipeline standards. A key identity: 1 lbf·s/ft² = 1 slug/(ft·s) ≈ 47.880 Pa·s = 478.8 P.
