Formula
Step-by-Step Example
Convert 5 lb/(ft·s) to pound-force seconds per square inch:
We need to convert pounds per foot second to pound-force seconds per square inch
Since 1 lbf·s/in² = 4633.0626194 lb/(ft·s), divide by 4633.0626194
5 ÷ 4633.0626194 = 0.0010791997
5 lb/(ft·s) = 0.0010791997 lbf·s/in²

About These Units
Pound per Foot Second (lb/(ft·s))
Pounds per foot-second (lb/(ft·s)) is an imperial viscosity unit equal to 1.488 Pa·s. Uses mass rather than force. Also called pound-mass per foot-second. Water at 20°C: 6.7×10⁻⁴ lb/(ft·s). Common in US fluid mechanics textbooks.
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.
