A Viscosity Converter is a tool used to convert between different units of viscosity. Viscosity is a measure of a fluid's resistance to flow. It describes how "thick" or "thin" a liquid is, which impacts its ability to flow under an applied force. For example, honey has a higher viscosity than water because it flows more slowly.

There are two main types of viscosity:

  1. Dynamic Viscosity (Absolute Viscosity): A measure of a fluid's internal friction. It's commonly used in engineering and physics. It is usually measured in poise (P) or pascal-seconds (Pa·s).

  2. Kinematic Viscosity: This refers to the dynamic viscosity divided by the fluid's density. It's used when studying the behavior of fluids in motion, particularly in pipes or flowing over surfaces. It is often measured in stokes (St) or centistokes (cSt).


Common Units of Viscosity:

  1. Pascal-seconds (Pa·s): The SI unit of dynamic viscosity.
  2. Poise (P): A unit of dynamic viscosity, often used in liquid measurement.
    • 1 P = 0.1 Pa·s
  3. Centipoise (cP): A smaller unit of poise, commonly used in industry.
    • 1 cP = 0.001 Pa·s
  4. Stokes (St): A unit of kinematic viscosity, commonly used in fluid mechanics.
    • 1 St = 10⁻⁴ m²/s
  5. Centistokes (cSt): A smaller unit of stokes, commonly used in industrial applications.
    • 1 cSt = 10⁻⁶ m²/s
