I don't think the difference between pounds and kilos really matters to purchasing food, but labeling everything with a per 100g nutrition facts rather than just whatever BS serving size the manufacturer makes up is a significant improvement. You can buy oil in the US that is listed as containing 0 calories and 0 fat per serving (and 1000+ servings per container). Not that that's a unit system issue.

As a calorie counter, I have thoughts on this. Comparing foods at the supermarket based on 100g base units is easier, true. But that means you need a scale every time you eat anything. It’s waaaay easier to go “yeah that’s about 1/3rd of the package” (and accurate enough for me).

So really I’d love nutritional labels that have both.

If everything was based on 100g, people would become used to roughly weighing things with their hands and knowing roughly how many calories are in their food.
