The A&W research firm organized focus groups. The results revealed that many participants mistakenly believed that one-third of a pound was smaller than one-fourth (quarter) of a pound. Focus group participants expressed confusion over the price, asking why they should pay the same amount for a “smaller” third-pound burger.
This misunderstanding stemmed from consumers focusing on the numbers “3” and “4,” leading them to conclude that one-third (1/3) was smaller than one-fourth (1/4), even though the opposite is true.[2]
A similar explanation appeared in The New York Times in 2014, citing the third-pound burger as one of the most vivid examples of consumer arithmetic failure.[3] In taste tests, customers actually preferred A&W’s burger to McDonald’s, and it was less expensive.
According to a CBC report, more than half of the people surveyed about the burger said they didn’t buy it because they thought they were getting less meat.[4]
This is even more interesting if you notice that Americans use fractions a lot, maybe even more than countries with metric system. It’s 1/2 pound, 5/8 inch, 3/4 mile and so on. Countries with metric system just change the units. Typically we don’t say 1/2 km, we say 500m.
That’s interesting. I never really noticed it but I’m not a fan of changing units. Whatever the “base unit” is for something is what I’ll use, even if it crosses the order of magnitude threshold.
Metric always gets decimal though, and sae units get fractions.
I’ve gotten myself switched to metric for kitchen weights and volume, and for small distances in projects I’m working on.
I’ll buy a 1/2 pound of meat, and then measure out 200 grams, with 100 ml of stock and 0.5 grams of something-small-i-cant-think-of-for-an-example-recipie.
Saying 500 milligrams feels wrong. So does asking for 1000 ml of pop though, since that’s the “wrong unit”.
I think there’s something baked into the American brain that says unit conversion is a source of error and should be avoided. Converting from 1 mile to 2640 feet is obviously gonna cause issues.
As for the fractions, I think that’s because sae units developed in a context where division by whole numbers was helpful, and metric was designed so that division by 10 was consistent and predictable.
Nothing intrinsically wrong with fractional units, other than 1/3 meter being a less reasonable number of centimeters than the inches in 1/3 yard.
Wikipedia confirmed though:

I suppose it’s much more rare for us to use 1/3 specifically. It does show up in cooking, but even there it’s hidden in the units a lot of the time.
Oof.
