Metric system overview

The European Pharmacopoeia (Ph. Eur.) has also adopted some of the apparatus designs (12) described in the USP, with some minor modifications in the specifications. Small but persistent differences between the two have their origin in the fact that the American metal processing industry, unlike the European, uses the imperial rather than the metric system. In the European Pharmacopeia, official dissolution testing apparatus for special dosage forms (medicated chewing gum, transdermal patches) have also been incorporated (Table 2 provides an overview of apparatus in Ph. Eur.). 

There are a myriad of effects resulting from the design and implementation of the rectangular land survey system ranging from agricultural field patterns and road patterns to even the U.S. resistance to the metric system. The purpose of this section is to provide overviews of the many effects the Rectangular Public Land Survey System had upon the landscape of the United States. We begin with Thomas Jefferson s emphasis upon the use of decimals.
