Kinematic viscosity measures resistance to flow of a fluid or "thikness" of a fluid. In the SI-system the theoretical unit is m2/s or commonly used Stoke: 1 St = 10-4 m2/s. Most common measurement unit for kinematic viscosity is centiStokes (cSt): 1 St = 100 cSt, 1 cSt = 10-6 m2/s
Kinematic viscosity is dependent on temperature. For liquids it usually decreases with increase in temperature whereas for gas it increases.
