About These Units
Pound-force Second per Square Foot (lbf·s/ft²)
Pound-force second per square foot (lbf·s/ft²) is the primary US imperial dynamic viscosity unit, equal to 47.88 Pa·s. Used in HVAC, hydraulics, and US engineering calculations. Also called poundal-second per square foot. Water is about 2.1×10⁻⁵ lbf·s/ft².
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.
