When measuring kinematic viscosity, it is important to specify which temperature it was measured for, because it differs with temperature for each substance. It is calculated as absolute viscosity divided by the density. Kinematic viscosity measures this resistance, as relative to the density of the substance. Absolute Viscosity and Kinematic ViscosityĪbsolute viscosity, also known as dynamic viscosity, measures the resistance of a fluid to a force that is acting upon it to make it flow. The latter is more often used in the automotive industry. There are two types of viscosity: absolute viscosity that is used more commonly in medicine, cosmetics, and cooking, and kinematic viscosity. Viscosity is a measure of internal resistance of fluid to the force causing the fluid to flow. This is what happens when a metal ball falls into a cup of non-viscous coffee
