About These Units
Pound-force Second per Square Inch (lbf·s/in²)
Pound-force second per square inch (lbf·s/in²) equals 6,895 Pa·s—very high viscosity scale. Equal to one reyn. Used for extremely viscous materials: pitch, tar, and high-pressure lubricant calculations. Water is only 1.45×10⁻⁷ lbf·s/in².
Poise (P)
The poise (P) is the CGS unit of dynamic viscosity equal to 0.1 Pa·s or 100 centipoise. Named after Jean Léonard Marie Poiseuille who studied blood flow. Water is 0.01 P, glycerin is ~15 P at 20°C. One poise = 1 g/(cm·s) = 1 dyn·s/cm².
