How to convert square feet per second to stokes
Kinematic viscosity is dynamic viscosity divided by density. The stokes equals one square centimeter per second. Temperature must match when comparing material data.
Use x for the value in ft²/s, b for the intermediate value in m²/s, and y for the result in St.
St = ft²/s × 0.09290304 ÷ 0.0001
Worked examples
10 ft²/s ≈ 9290.304 St
Step 1: (10 × 0.09290304) ≈ 0.9290304 m²/s.
Step 2: 0.9290304 ÷ 0.0001 ≈ 9290.304 St.20 ft²/s ≈ 18580.608 St
Step 1: (20 × 0.09290304) ≈ 1.8580608 m²/s.
Step 2: 1.8580608 ÷ 0.0001 ≈ 18580.608 St.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Square feet per second
Square feet per second (ft²/s) measures viscosity kinematic under the conventions above. The base value in m²/s is (x × 0.09290304), where x is the numerical value in ft²/s. Factors shown here are rounded for display; calculations use the stored factor.
About Stokes
Stokes (St) measures viscosity kinematic under the conventions above. The base value in m²/s is (x × 0.0001), where x is the numerical value in St. Factors shown here are rounded for display; calculations use the stored factor.
