The pascal-second (Pa·s) is the SI unit of dynamic viscosity, the measure of a fluid's resistance to shear. It is defined as one newton-second per square meter, equivalently kg/(m·s). The unit is derived within the International System of Units and is named after Blaise Pascal.
Dynamic viscosity expresses how a liquid deforms under applied shear stress. Fluids with higher viscosity flow
In related units, 1 Pa·s equals 10 Poise and 1 Pa·s equals 1000 centipoise (cP). Since a
