# What Is the Viscosity of Water?

Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. The viscosity of water or fluid is depends on temperature, shear rate and time. The flow behaviour is characterized as Thixotropic and Rheopetic depending on how viscosity changes.
The dynamic viscosity of water is 0.89 Cp at about 25 degrees Celsius. Water has a viscosity of 0.0091 poise at 25 degrees Celsius or 1 centipoise at 20 degrees Celsius. Viscosity is the measure of resistance of a fluid being deformed by tensile or shear stress.
The viscosity of water at 100 degrees Fahrenheit is 1.423 in Dynamic Viscosity, and 0.738 Kinematic Viscosity Imperial Units (BG units). It get thinner as it gets hotter and thicker as it gets colder.
The standard viscosity is the viscosity of water. The viscosity of water changes with its temperature. But at 25°C it is 8.90 × 10?4 Pa·s. Viscosity is a fluid's resistance to flow.
