# What is Dimensional Formula of Kinematic viscosity?

Posted in Dimensional Formulae | Email This Post |Kinematic viscosity is defined as the ratio of ability to diffuse a disturbance in momentum to ability of sustaining the original momentum.

Mathematically,

Kinematic viscosity (ν) = Dynamic viscosity (μ) / Density (ρ).

Dimensional Formula of Dynamic viscosity = M^{1}L^{-1}T^{-1}

Dimensional Formula of Density = M^{1}L^{-3}T^{0}

Putting these values in above equation we get,

**Dimensional Formula of Kinematic viscosity = M ^{0}L^{2}T^{-1}**

SI unit of Kinematic viscosity is m^{2}s^{-1}
