Viscosity Converter
Convert between Pascal-second, centipoise, and other viscosity units
Dynamic viscosity (μ) measures internal fluid friction - force per unit area needed to create flow (Pa·s). Water at 20°C: 0.001 Pa·s.

Viscosity Facts
- Viscosity is a measure of a fluid's resistance to flow or deformation when subjected to stress.
- Temperature significantly affects viscosity - most liquids become less viscous when heated, while gases become more viscous.
- Newtonian fluids (like water and oil) maintain constant viscosity regardless of applied force.
- Non-Newtonian fluids (like ketchup, blood, and quicksand) change viscosity when force is applied.
- Kinematic viscosity (ν) = Dynamic viscosity (μ) / Density (ρ).
Applications of Viscosity
Viscosity measurements are crucial in various industries:
- Automotive - motor oil performance and engine protection
- Food processing - consistency of sauces, dairy products, and beverages
- Pharmaceuticals - medicine formulations and injectable solutions
- Petroleum - oil drilling fluids and fuel performance
- Manufacturing - paint application, coatings, and adhesives
- Cosmetics - lotions, creams, and makeup products
- Medical diagnostics - blood viscosity as a health indicator
The Stokes-Einstein equation relates diffusion coefficient to viscosity, connecting molecular movement to macroscopic fluid behavior.
