Kinematic viscosity measures a fluid's resistance to flow under gravity, defined as dynamic viscosity divided by density.
The square meter per second is the SI derived unit, while the centistoke is the standard practical unit in the oil and lubricant industry.

What is kinematic viscosity?
Kinematic viscosity is the ratio of a fluid's dynamic viscosity to its density.
It is central to fluid mechanics calculations such as the Reynolds number and pipe flow analysis.
Square meters per second and centistokes
The centistoke (cSt), equal to 1 mm²/s, is the most common practical unit used in the oil and lubricant industry for engine oil grading.
