4 C) Only approximately equivalent to the metric values in column 1. d) These Sieves are not in the Standard series but they have been included because they are in common usage. e) These numbers (3 1/2 to 635) are the approximate number of openings per linear inch, but it is preferred that the sieve be identified by the Standard designation in millimeters or micrometers. f) 1,000 m=1 mm
