How to Convert Kinematic Viscosity Units
Kinematic viscosity is dynamic viscosity divided by density (ν = μ / ρ). The SI unit is square metre per second (m²/s); oils and lubricants are graded in centistokes (cSt), equal to mm²/s.
Every unit on this page is stored as a fixed factor relative to one reference unit, the sq metre per second (m²/s). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in m²/s.
- Divide that result by the factor of the target unit.

Frequently Asked Questions
What is the SI unit of kinematic viscosity?
The SI unit of kinematic viscosity is the sq metre per second (m²/s). Kinematic viscosity is dynamic viscosity divided by density (ν = μ / ρ).
How do I convert cSt to m²/s?
To convert centistokes (cSt) to sq metre per second (m²/s), multiply the value in cSt by 0.000001. For example, 1 cSt = 0.000001 m²/s.
How do I convert St to cSt?
To convert stokes (St) to centistokes (cSt), multiply the value in St by 100. For example, 1 St = 100 cSt.
How do I convert ft²/s to cSt?
To convert sq foot per second (ft²/s) to centistokes (cSt), multiply the value in ft²/s by 92,903. For example, 1 ft²/s = 92,903 cSt.
Can I see a value in every kinematic viscosity unit at once?
Yes. Enter a value and choose the source unit; the "all units" table below the converter instantly lists the equivalent in all 9 supported units. Click any row to make it the target unit.
