How to convert stokes to centistokes
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 cSt.
cSt = St × 0.0001 ÷ 0.000001
Worked examples
10 St ≈ 1000 cSt
Step 1: (10 × 0.0001) ≈ 0.001 m²/s.
Step 2: 0.001 ÷ 0.000001 ≈ 1000 cSt.20 St ≈ 2000 cSt
Step 1: (20 × 0.0001) ≈ 0.002 m²/s.
Step 2: 0.002 ÷ 0.000001 ≈ 2000 cSt.
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 Centistokes
Centistokes (cSt) measures viscosity kinematic under the conventions above. The base value in m²/s is (x × 0.000001), where x is the numerical value in cSt. Factors shown here are rounded for display; calculations use the stored factor.
