It is defined as the ratio of dynamic viscosity to density. The dynamic viscosity is a measure of how much resistance a fluid offers to deformation, while the density is a measure of how much mass a fluid contains per unit volume.<\/p>\n<p>The units of kinematic viscosity are cm2\/sec. This can be written in other ways, such as m2\/s or ft2\/s. The units of kinematic viscosity are derived from the units of dynamic viscosity and density. The units of dynamic viscosity are dyne-sec\/cm2, and the units of density are g\/cm3. Therefore, the units of kinematic viscosity are dyne-sec\/cm2 \/ g\/cm3 = cm2\/sec.<\/p>\n<p>Option A, gm\/cm-sec2, is not a correct unit of kinematic viscosity.
