FAQ
What is the conversion factor from cSt to ft²/s?
1 cSt equals 1.076391e-5 ft²/s. To convert, multiply the value in centistokes by 1.076391e-5.
How do I convert 1 cSt to ft²/s?
1 cSt = 1.07639e-5 ft²/s. For any value, multiply by 1.076391e-5.
How do I convert ft²/s back to cSt?
Divide by the same factor — or equivalently, multiply by 92903.04. So 1 ft²/s = 92903 cSt.
When would I need to convert centistoke to square foot per second?
Kinematic viscosity conversions between cSt and ft²/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).
