Kinematic Viscosity Calculator


Dynamic viscosity: Nsm-2
Kinematic viscosity: m2s-1
Density: kgm-3

Kinematic viscosity is the ratio of the dynamic viscosity of a liquid to the density ρ of the fluid at the same temperature. The unit is (m^2)/s. It is represented by the lowercase letter v. Note: The unit that has been used is St. The relationship between St and (m^2)/s is: 1(m^2)/s=10^4St=10^6cSt. ("cSt" is read as "centistokes") The flowing liquid is regarded as many liquid layers moving parallel to each other, and the speed of each layer is different, forming a velocity gradient (dv/dx), which is the basic characteristic of flow.

Formula v = m/p

v = kinematic viscosity [m2s-1]

m = dynamic viscosity [Nsm-2]

ρ = density [kgm-3]
