If I understand correctly, the FPLA ( https://en.wikipedia.org/wiki/Fair_Packaging_and_Labeling_Act https://en.wikipedia.org/wiki/Fair_Packaging_and_Labeling_Ac... ) requires grocery items to be labeled in both American units and metric units. Metric-only is illegal in America but legal and common in Canada. I have shopped in American and Canadian supermarkets and speak from personal observations. It seems the exception is that wine imported into the US can keep metric-only labeling, so I have indeed seen bottles labeled only "750 mL", sold in the US.
