Formula
Formula
cSt = mm²/s × 1
Multiply any value in square millimetres per second by 1 to obtain the value in centistokes.
Worked example
Convert 1 mm²/s to cSt.
- 01Start with 1 mm²/s.
- 02Multiply by the conversion factor: 1 × 1 = 1 cSt.
Result1 mm²/s = 1 cSt

FAQ
What is the conversion factor from mm²/s to cSt?
1 mm²/s equals 1 cSt. To convert, multiply the value in square millimetres per second by 1.
How do I convert 1 mm²/s to cSt?
1 mm²/s = 1 cSt. For any value, multiply by 1.
How do I convert cSt back to mm²/s?
Divide by the same factor — or equivalently, multiply by 1. So 1 cSt = 1 mm²/s.
When would I need to convert square millimetre per second to centistoke?
Kinematic viscosity conversions between mm²/s and cSt 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).
