Kinematic viscosity measures a fluid's internal resistance to flow under the weight of gravity. It is defined as the ratio of dynamic viscosity to the density of the fluid:

Dynamic viscosity = N.S/m2 = kg/m2s2xs = kg/ms.
Density = kg/m3.
Dynamic Viscosity/density = kg/msxm3/kg = m2/s.

Kinemetic viscocity k = dynamic viscocity/density.
Dynamic viscocity = N-sec/m^2.
Density = kg/m^3.
Hence K = (N-sec/m^3)/(kg/m^3).
1N = Kg-m/s^2.
So, K = ((Kg-m/s^2)/m^3)/(kg/m^3).
K = m^2/s.

Dynamic viscocity = N-sec/m^2.
Density = kg/m^3.
Hence K = (N-sec/m^3)/(kg/m^3).
1N = Kg-m/s^2.
So K = ((Kg-m/s^2)/m^3)/(kg/m^3).
K = m^2/s.

kinametic viscocity k = dynamic viscocity/density.
Dynamic viscocity = N-sec/m^2.
Density = m^3/sec.
Hence K= N-sec/m^3/m^3/sec.
k = N/m^2.
