Most people hate math and will avoid it at all costs. Most people don't even bother trying to figure out if buying two quarts of ice cream is cheaper than buying a half gallon, and many couldn't do it if they tried. They buy by visual size and assume the bigger size is cheaper per unit. They buy two liter bottles of soda, half liter bottles of water and other metric packaging without hesitation, simply by visually looking at the size without even looking at the net contents. ANY and ALL conversion tables (that look like math) or any other attempts to educate them, will turn people off and are counterproductive.

I think part of the problem in the US of metrication is conversional magnitude. A major transitionary step to metric acceptance would be to require legacy units and conversions to be “magnitude compatible”—e.g., convert and express liters strictly as quarts, not gallons, and meters as yards, not feet. Likewise, the metric prefixes should be as magnitude compatible as possible, too: oz.⬌dag; floz.⬌cL; ft⬌dm; yd⬌m; in.Hg⬌cmHg⬌kPa; What is more conversionarily palpable— Gas: “$2.00/gal. ≈ $0.53/L ” or “$0.50/qt.≈ $0.53/L ”?; Food: “16 Fl oz. (473 mL)” or “16 Fl oz. (47.3 cL)”?; “8 Oz. (227 g)” or “8 Oz. (22.7 dag)“?; Bar.: “1021 hPa“ or ”102.1 kPa”?; “765.3 mmHg” or “76.53 cmHg”?; (compared to 30.13 in.Hg) BP: “115/73 mmHg” or “11.5/7.3 cmHg”?
