# Kinematic Viscosity and Dynamic Viscosity

Difference between kinematic viscosity and dynamic viscosity and discuss the units in S.I and C.G.S system.

Kinemetic Viscosity is the ratio of absolute viscosity to density whereas dynamic viscosity is resistance offered by one layer of fluid with another having unit surface area seperated by unit distance.

In simpler way, viscosity is defined as the resistance to flow. Simple viscosity is also termed as dynamic viscosity. But if dynamic viscosity is divided by density then it is kinematic viscosity. Unit of dynamic viscosity is m^2/sec or poise. For kinematic viscosity the unit is stoke newton-sec/m^2.

Kinematic viscocity is the ratio of dynamic viscocity to density of the fluid.

Dynamic viscosity is a measure of a fluid's resistance to shear flow.

Kinematic viscosity is a ratio of the dynamic viscosity and density of a fluid,

Kinematic is related to the cross section of fluid passing through an area in a unit of time.

Dynamic is related to the mass quantity per (meter * second) passing through a volume of space.
