Fluid viscosity is an important property in the analysis of liquid behavior and fluid motion near solid boundaries.
The viscosity is fluid resistance to shear or flow and is a measure of the adhesive (cohesive) or frictional properties of a fluid. The resistance is caused by inter-molecular friction exerted when layers of fluids attempts to slide by an other.
A Dynamic or Absolute Viscosity Units Converting Table
The table below can be used to convert between common dynamic or absolute viscosity units.

Example - Converting Dynamic Viscosity from centipoise to lb/ft s
From the table above - to convert from centipoise (cP) to lb/ft s - centipoise must be multiplied with 0.000672.
10 centipoise can then be converted like
(10 centipoise) 0.000672 = 0.00672 lb/ft s
