What is dynamic viscosity?
Viscosity is a fluid's resistance to flow: honey is viscous, water much less so. Dynamic (or absolute) viscosity is the ratio of shear stress to shear rate. Its SI unit is the pascal-second (Pa·s); the CGS unit is the poise, and the centipoise (cP) is the most common in practice because water at 20 °C has a viscosity of almost exactly 1 cP (1 mPa·s).
Dynamic viscosity divided by density gives kinematic viscosity, measured in stokes and centistokes; see the kinematic viscosity converter. Converting between the two needs the fluid's density.

Frequently asked questions
How many centipoise is 1 Pa·s?
1 Pa·s = 1,000 cP = 10 P.
How do I convert centipoise to centistokes?
Divide by the fluid's density in g/cm³: cSt = cP ÷ density. For water (about 1 g/cm³) the numbers are almost the same.
