How to convert stokes to square feet per second
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 St, b for the intermediate value in m²/s, and y for the result in ft²/s.
ft²/s = St × 0.0001 ÷ 0.09290304
Worked examples
10 St ≈ 0.0107639104167 ft²/s
Step 1: (10 × 0.0001) ≈ 0.001 m²/s.
Step 2: 0.001 ÷ 0.09290304 ≈ 0.0107639104167 ft²/s.20 St ≈ 0.0215278208334 ft²/s
Step 1: (20 × 0.0001) ≈ 0.002 m²/s.
Step 2: 0.002 ÷ 0.09290304 ≈ 0.0215278208334 ft²/s.
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 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.
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.
