This is also common in the US.

Example below. Top row is blurry but bottom row shows “per ounce” price on the bottom right. Tiny print and I imagine barely anyone actually shops that way.

I’m guessing there must be some US requirement for this otherwise I’m not sure why it’s commonplace.

This feels so foreign to me; I largely ignore the overall price and shop by unit prices within a reasonable size range.

I think the commenter you are responding to does not have enough faith in humanity. Most people I know (anecdotal and biased sampling I know) do check that number when shopping, especially for interchangeable items that don't have a well-know brand such as flour or baking powder.

Ancidotal, but myself and many of my friends shop this way. I've found that sometimes the larger bottle isn't cheaper per unit
