Jim Frysinger and Jim Steele have persuaded me that comment on the current Notice by the FTC in the Federal Register can be important for the advancement of SI in the USA.
Consider the detailed wording of (1) the existing FPLA, and (2) the nearly completed initiative at NIST to develop a Guide for Unit Pricing. A word by word examination of the existing FPLA reveals that only *total amounts* of a product contained in a package for consumers must be declared on labels in dual units; metric and not metric, e.g. grams and ounces. There is absolutely *no mention* of the units required for “Unit Pricing” or even mention of the term “Unit Pricing” in the existing FPLA. In other words, there is *no legal exclusion* of Unit Pricing in *metric-only* units. e.g. cents per gram” in “dollars per kilogram” In “cents per milliliter”, etc. by the enforcers of the existing FPLA! I plan to recommend, in response to the Notice by the Federal Trade Commission, that the FTC adopt a rule that permits *metric only* Unit Pricing of commodities regulated by the FTC. Eugene Mechtly
