cSttoSt
Convert centistokes (cSt) to stokes (St).
Factor1 cSt = 0.01 St
Converter
cSt
Accepts numbers or expressions, e.g. 150 + 14.7
Result
St
Rendered to 6 significant figures.
Formula
Formula
St = cSt × 0.01
Multiply any value in centistokes by 0.01 to obtain the value in stokes.
Worked example
Convert 100 cSt to St.
- 01Start with 100 cSt.
- 02Multiply by the conversion factor: 100 × 0.01 = 1 St.
Result100 cSt = 1 St

FAQ
What is the conversion factor from cSt to St?
1 cSt equals 0.01 St. To convert, multiply the value in centistokes by 0.01.
How do I convert 1 cSt to St?
1 cSt = 0.01 St. For any value, multiply by 0.01.
How do I convert St back to cSt?
Divide by the same factor — or equivalently, multiply by 100. So 1 St = 100 cSt.
When would I need to convert centistoke to stoke?
Kinematic viscosity conversions between cSt and St arise in hydraulic fluid selection, lubricant grading (ISO VG), pipe flow Reynolds number calculations, and fuel-oil specification. Kinematic viscosity equals dynamic viscosity divided by fluid density and cannot be directly compared to dynamic viscosity without that context.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
