Note: The precision of conversion in this table is limited by two factors. It assumes that the density of liquids is 1 so that
stokes and poises are the same and that viscosity is independent of shear rate, I.e., the fluid is Newtonian. To correct for
density in converting from centistokes to centipoises, multiply specific gravity by centistokes.
