How to Convert Centistokes to Square Meter per Second
- 1 cSt = 0.000001 m²/s
- 1 m²/s = 1000000 cSt
- Example: convert 15 cSt to m²/s: 15 cSt = 15 × 0.000001 m²/s = 0.000015 m²/s
Formula
m²/s = cSt ÷ 1000000
Derivation from SI units:
- 1 cSt = 0.01 St = 10⁻⁶ m²/s = 1 mm²/s
- 1 m²/s = 1 m² ÷ 1 s
Both units are defined exactly, so the factor is exact. Centistokes definition: centistokes; Square Meter per Second definition: square meter per second.
Worked examples
- Water at about 1 cSt is 0.000001 m²/s.
1 cSt × 0.000001 = 0.000001 m²/s - A 100 cSt oil is 0.0001 m²/s.
100 cSt × 0.000001 = 0.0001 m²/s

Frequently asked questions
How do I use cSt in the Reynolds number?
Convert to m²/s first, then Re = v × D / ν with v in m/s and D in m. 10 cSt = 0.00001 m²/s.
How many square meters per second are in 1 centistokes?
1 cSt = 0.000001 m²/s.
How do I convert centistokes to square meters per second?
Multiply the value in cSt by 0.000001, or divide it by 1000000. For example, 15 cSt × 0.000001 = 0.000015 m²/s.
Is the cSt to m²/s conversion exact?
Yes. Both units are defined exactly, and 1 cSt is exactly 0.000001 m²/s.
