Viscosity Converter (Dynamic)

About This Tool

This Dynamic Viscosity Converter is an essential tool for fluid mechanics, chemical engineering, and material science. It converts units of dynamic viscosity (also called absolute viscosity), which measures a fluid's internal resistance to flow. The base unit is the Pascal-second (Pa·s).

A fluid with high dynamic viscosity, like honey, resists motion more strongly than a fluid with low dynamic viscosity, like water. This property is crucial for designing lubrication systems, analyzing fluid flow in pipes, and formulating products like paints and cosmetics.

Tips & Features

• Understanding Viscosity: Dynamic viscosity quantifies the 'thickness' or 'stickiness' of a fluid. It represents the shear stress needed to move a fluid layer at a certain velocity relative to another layer.
• Poise and Centipoise (cP): The centipoise (cP) is a very common CGS unit. The viscosity of water at room temperature is conveniently about 1 cP, making it a practical reference. 1 cP = 0.001 Pa·s.
• Dynamic vs. Kinematic Viscosity: Dynamic viscosity (μ) is an absolute measure of a fluid's resistance to shear. Kinematic viscosity (ν) is the ratio of dynamic viscosity to the fluid's density (ν = μ/ρ) and describes how easily a fluid flows under the influence of gravity.
