What does viscosity measure in a product?

Viscosity measures the thickness or liquidity of a product, indicating how resistant it is to flow. In simple terms, it describes how easily a fluid can move. A substance with high viscosity, like honey, flows slowly due to its thickness, while a substance like water, which has low viscosity, flows easily and quickly. Understanding viscosity is important in many applications, such as in cosmetics, food products, and industrial materials, as it affects how products behave and perform. This measurement helps determine how appropriate a material is for various uses, influencing factors like application methods and drying times.
