Poise, base units

Viscosity, as it was defined in Equation (15.1), is often called the dynamic viscosity. The most common unit of dynamic viscosity is the centipoise, a unit based on force per rate. The base unit, the poise (100 centipoise per poise) is seldom used. Of more practical significance is kinematic viscosity, which is the dynamic viscosity divided by the density of the fluid ... 

Pharmacy educators are poised to adapt to the changes in practice that will result from the widespread adoption of drug therapies based on pharma-cogenomics. Pharmacy education has been in a constant state of evolution since the early twentieth century, when the education of pharmacists consisted almost entirely of basic chemistry applied to those compounds thought to be useful as medications. At that time, many academic pharmacy programs were housed in departments of chemistry. Schools and colleges of pharmacy now are independent academic units, many of which are fully integrated into major academic health science centers. 

The original unit for viscosity was based on the cgs system, where the viscosity is given in dyne s cm". This unit, which is termed a Poise and given the symbol P, is used in virtually all literature prior to 1970 and is still used extensively throughout the glass industry. In SI units, which have replaced cgs units in much of the recent literature, viscosity is given in N s m", or, since a Pascal is a N m, the viscosity is reported in Pa s. Since 1 Pa s = 10 P, the conversion of viscosity data from one unit to the other is very straightforward. The viscosity of water at room temperature is 0.01 P, or 0.001 Pa s.
