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.
Square Inch per Second (in²/s)
Square inches per second (in²/s) equals 6.45 stokes or 645 centistokes. Used for moderate viscosity materials in imperial units. Water at 20°C: 1.55×10⁻³ in²/s. One ft²/s = 144 in²/s. Common in smaller-scale US engineering applications.
