In almost every European country, stores must show the price per liter or kg.

  At least in Germany shops play rather loosely with the units. Yes, you have €/kg but you also have €/100g, €/g, ... and they will switch between them even for near identical products. Can't cheat buyers out of money by selling them a 30% larger bottle if you make it too obvious that they are paying 40% more for it.

    I’m puzzled by this. How hard is it to convert prices by powers of 10? Do the same thing with $/lb and $/oz, and I’d be lost. Edit: Oh wait, I get it. It’s just that a price per 100 g is an order if magnitude less than per kg, so psychology kicks in and makes it look cheaper, even though the conversion is trivial. A bit like the 9.99 effect.

    But this could just be part of the pattern of Europeans being more lose with unit changing, because it's so easy to do anyway. People just tend to use the units that keep the values in a reasonable range of 1-10.
