How to Convert Centistokes to Stokes
- 1 cSt = 0.01 St
- 1 St = 100 cSt
- Example: convert 15 cSt to St: 15 cSt = 15 × 0.01 St = 0.15 St
Formula
St = cSt ÷ 100
Derivation from SI units:
- 1 cSt = 0.01 St = 10⁻⁶ m²/s = 1 mm²/s
- 1 St = 1 cm²/s = 10⁻⁴ m²/s
- 1 cSt = 0.000001 m²/s ÷ 0.0001 m²/s per St = 0.01 St
Both units are defined exactly, so the factor is exact. Centistokes definition: centistokes; Stokes definition: stokes.
Worked examples
- A 350 cSt silicone fluid is 3.5 St.
350 cSt × 0.01 = 3.5 St - 1000 cSt is 10 St.
1000 cSt × 0.01 = 10 St

Frequently asked questions
Is a stokes 1 cm²/s?
Yes, exactly.
How many stokes are in 1 centistokes?
1 cSt = 0.01 St.
How do I convert centistokes to stokes?
Multiply the value in cSt by 0.01, or divide it by 100. For example, 15 cSt × 0.01 = 0.15 St.
Is the cSt to St conversion exact?
Yes. Both units are defined exactly, and 1 cSt is exactly 0.01 St.
