it is an EU thing [0][1] Easy comparison – price per unit You should also be able to compare prices between brands and between package sizes – to see, for example, what saving you'd make buying a large-size box of breakfast cereal instead of a small box. To help you do this, all products must be marked not only with the selling price, but also the price per unit – for example, the price per kilo or per litre. This information must be understandable, easy to read, and easily identifiable. This rule also applies to adverts that mention a selling price. Notice this does not apply uniformly since it delegates to national regulations, so e.g. IIRC in Italy supermarkets list the number of "bits" you can rip off a toilet paper roll, but in Hungary they don't. ^0 https://commission.europa.eu/law/law-topic/consumer-protection-law/unfair-commercial-practices-law/price-indication-directive_en https://commission.europa.eu/law/law-topic/consumer-protecti... ^1 https://europa.eu/youreurope/citizens/consumers/unfair-treatment/unfair-pricing/index_en.htm https://europa.eu/youreurope/citizens/consumers/unfair-treat...
