Every packet carries a small table, but per 100 g and per portion answer different questions. Per 100 g lets you compare products fairly; per portion tells you what you actually eat.
Type in any label's numbers, set how many grams you serve, and the reader shows your serving, its share of the EU reference intakes and a high, medium or low rating per 100 g. It's general information, not medical advice.

A basic stainless-steel scale that covers what the guide asks for: weigh a bowl, then check a portion of cereal or rice against the label. Fine for learning what 30 g or 60 g looks like.
A step up for people who plan to keep weighing. Two platforms make it easier to measure ingredients separately when you compare per 100 g numbers with what you actually serve.
A design-led scale that is nice enough to leave on the counter. The extra cost is mostly looks and build, not necessarily better portions, so it only suits you if a tidy kitchen helps you keep the habit.
