Important Notice
Design values are presented in this document in both metric and U.S. customary units and were developed independently within each system. The relationship between the metric and U.S. customary values is neither an exact (soft) conversion nor a completely rationalized (hard) conversion. The metric values are those that would have been used had this document been presented exclusively in metric units; The U.S. customary values are those that would have been used if this document had been presented exclusively in U.S. customary Units. Therefore, the user is advised to work completely in one system and not attempt to convert directly between the two.
