How to Convert Pound-force Seconds per Square Foot to Pascal Seconds
The pound-force second per square foot and pascal second are both units of viscosity. 1 pound-force second per square foot equals 47.88026 pascal seconds. This means to convert pound-force seconds per square foot to pascal seconds, you multiply by 47.88026.
Formula
Step-by-Step Example
Convert 5 lbf·s/ft² to pascal seconds:
We need to convert pound-force seconds per square foot to pascal seconds
Since 1 lbf·s/ft² = 47.88026 Pa·s, multiply by 47.88026
5 × 47.88026 = 239.4013
5 lbf·s/ft² = 239.4013 Pa·s

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.
Pascal Second (Pa·s)
The Pascal second (Pa·s) is the SI unit of dynamic (absolute) viscosity—a fluid's resistance to shear flow. Water at 20°C: 0.001 Pa·s, motor oil: 0.1-0.3 Pa·s, honey: 2-10 Pa·s, molten glass: 10-1000 Pa·s. Formula: τ = η × (dv/dy). One Pa·s = 10 poise = 1000 centipoise.
