The coefficient of viscosity, denoted by the symbol "η", is defined as the ratio of the tangential force per unit area to the velocity gradient perpendicular to the direction of flow. The SI unit of viscosity is the pascal-second (Pa·s), and its dimensions can be derived using the formula: 

[\eta ]=[F] [L^{-2}] [T] [L^{-1}] = [ML^{-1}T^{-1}].
