Definition: Viscosity is a measurement of how resistant a fluid is to attempts to move through it. A fluid with a low viscosity is said to be thin, while a high viscosity fluid is said to be thick.. It is easier to move through a low viscosity fluid (like water) than a high viscosity fluid (like honey).

It is used to characterize lubricating oil in the automotive industry. The viscosity of liquids decreases as temperature increases. The viscosity of a lubricant is closely related to its ability to reduce friction.
