NOTE: Paper Weight Equivalence Table Use this table to determine approximate equivalent points in weight specifications other than U.S. bond weight. For example, to determine the equivalent of 20 lb U.S. bond weight paper in U.S. cover weight, locate the bond weight (in row 3, second column) and scan across the row to the cover weight (in the fourth column). The equivalent is 28 lb. Table 2-9.

Use for reference only. Metric Sizes For metric size paper (A4), use the following method to determine basis weight. Take 16 sheets of A4 paper and weigh them. One square meter of paper contains approximately 16 A4 size sheets. Compare this weight to the appropriate weight in "Paper Weight Equivalence" (page 39). Caliper Field Test Specification: The specified caliper differs with the type of media used. See "Operating Requirements" (page 25) for additional information. Caliper can be measured in the field using a micrometer. C4170-90959 Media Specifications 39
