Formula
Formula
cm²/s = St × 1
Multiply any value in stokes by 1 to obtain the value in square centimetres per second.
Worked example

FAQ
What is the conversion factor from St to cm²/s?
1 St equals 1 cm²/s. To convert, multiply the value in stokes by 1.
How do I convert 1 St to cm²/s?
1 St = 1 cm²/s. For any value, multiply by 1.
How do I convert cm²/s back to St?
Divide by the same factor — or equivalently, multiply by 1. So 1 cm²/s = 1 St.
When would I need to convert stoke to square centimetre per second?
Kinematic viscosity conversions between St and cm²/s 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).
