標準簡介
1.1 This abbreviated metric practice guide provides a table of conversion factors for expressing units of measure peculiar to the roofing industry as exact metric units. This guide is based on Practice E 380. Relationships that are exact in terms of the base unit are followed by an asterisk. Relationships that are not followed by an asterisk are either the result of physical measurements or are only approximate.
