MillipascalSekunden

MillipascalSekunden is a unit of dynamic viscosity. It is derived from the base SI units of the pascal, meter, and second. A pascal is the SI unit of pressure, equivalent to one newton per square meter. Dynamic viscosity measures a fluid's resistance to shear flow. In simpler terms, it describes how "thick" or "sticky" a fluid is.

The unit is constructed as follows: one pascal-second (Pa·s) represents the dynamic viscosity of a fluid where a shear stress of one pascal results in a velocity gradient of one reciprocal second. The millipascal-second (mPa·s) is one-thousandth of a pascal-second. This means that 1 Pa·s = 1000 mPa·s.

MillipascalSekunden is frequently used in various scientific and engineering fields, particularly when dealing with fluids that have low viscosity, such as water or many organic solvents. For instance, the dynamic viscosity of water at room temperature is approximately 1 millipascal-second. This unit offers a more convenient scale for measuring and comparing the viscosities of such common liquids, avoiding the need for large numbers when expressing values. It is also sometimes referred to as centipoise, as 1 millipascal-second is equivalent to 1 centipoise (cP), where the centipoise is a non-SI unit still widely used in many industries.
