How to convert square millimeters 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 mm²/s, b for the intermediate value in m²/s, and y for the result in St.
St = mm²/s × 0.000001 ÷ 0.0001
Worked examples
10 mm²/s ≈ 0.1 St
Step 1: (10 × 0.000001) ≈ 0.00001 m²/s.
Step 2: 0.00001 ÷ 0.0001 ≈ 0.1 St.20 mm²/s ≈ 0.2 St
Step 1: (20 × 0.000001) ≈ 0.00002 m²/s.
Step 2: 0.00002 ÷ 0.0001 ≈ 0.2 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 millimeters per second
Square millimeters per second (mm²/s) measures viscosity kinematic under the conventions above. The base value in m²/s is (x × 0.000001), where x is the numerical value in mm²/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.
