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.
Stokes (St)
The stokes (St) is the CGS unit of kinematic viscosity equal to 1 cm²/s or 100 centistokes. Named after physicist George Stokes. Water at 20°C: 0.01 St, light motor oil: 0.3-1 St at 40°C. One stokes = 10⁻⁴ m²/s. Common in technical literature.
