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.

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.
