Dear Professionals in the Field of Legal Metrology, As a persistent advocate of SI and as an indirect-partial employer of NIST personnel, I request that the contents of NIST Handbooks 130 and 133 be deliberated edited to completely separate provisions expressed in SI Units of Measurement from provisions expressed in units from outside the SI (in so-called US Customary or inch-pound units).
Full justification for this separation is Federal Laws which declare the International System of Units (SI) as the *Preferred* System of Units of Measurement for Trade and Commerce in the United States. The objective, of course, it efficient transition to SI-only regulation of consumer commodities in retail marketplaces when SI-only labels become permitted by amendment of the FPLA or by rulings of the FTC, USDA, FDA, ATF and other federal agencies, or by prevailing practices in the States, irrespective of the entangled wordings of provisions which continue to be drafted by the NCWM.
