Formula
Step-by-Step Example
Convert 5 St to pound-force seconds per square foot:
We need to convert stokes to pound-force seconds per square foot
Since 1 lbf·s/ft² = 478802.6 St, divide by 478802.6
5 ÷ 478802.6 = 1.0442716894e-5
5 St = 1.0442716894e-5 lbf·s/ft²

About These Units
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.
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.
