What is the difference between dynamic and kinematic viscosity?

Dynamic (absolute) viscosity measures a fluid's internal resistance to flow under an applied external shear force (measured in Pa·s or cP). Kinematic viscosity measures flow resistance under gravitational force, calculated by dividing dynamic viscosity by density (measured in cSt or m²/s).

How many Centipoise (cP) are in 1 Pascal-second?

1 Pascal-second (Pa·s) equals exactly 1,000 Centipoise (cP) or 10 Poise (P). For reference, pure water at 20°C has a dynamic viscosity of almost exactly 1.0 cP.

Understanding Fluid Viscosity

Viscosity measures a fluid's internal friction or resistance to gradual deformation by shear stress. Thin liquids like water and alcohol flow readily and have low viscosity (~1 cP), while thick fluids like motor oils, honey, and peanut butter resist flow and possess high viscosity.

Frequently Asked Questions

How do you convert Centipoise to Centistokes?

Kinematic Viscosity (cSt) = Dynamic Viscosity (cP) / Density (g/cm³). For water with density of 1.0 g/cm³, 1 cP equals exactly 1 cSt.

What does SUS stand for in oil ratings?

Saybolt Universal Seconds (SUS or SSU) measures the time in seconds for 60 mL of oil to flow through a calibrated Saybolt viscometer orifice at 100°F or 210°F.
