I don't own a current copy and don't see a need for one. The SI Brochure, and NIST SP330 and SP811 suffice for my purposes and heavily overlap the content. However, I had a copy in the early 70's. I was helping the electronics company I worked for then go metric, in addition to my regular engineering duties. As I recall, it had some information helpful to organizations transitioning from Customary or dual to metric, particularly on rounding. (Rounding nominal or target values is pretty straightforward; rounding minimum and maximums from specs requires either rounding "specward" or some engineering judgementor both.) I don't feel it is needed in organizations that ARE metric, but that is a personal opinion and others may feel differently. Also, it is (at least partially) out of date whenever a new edition of the SI Brochure comes out. It takes time for the NIST and ANSI publications to catch up. (although revisions from 7th to 8th SI Brochure are not earthshaking)
