I have seen "per 100 g" a lot at deli counters there. Most people don't buy over 1 kg of ham, of cheese, etc. so 100 g is closer to quantities they actually do purchase. My American-born friend Barbara (a fellow native San Franciscan like me) who married a UK professor in 1976 lives in Kenilworth, south of Coventry. She likes to shop every day. She goes to the local Waitrow's or Sainsbury's and asks for "a quarter" of ham, of cheese, etc. Although to the old-timers this means a quarter-pound, by convention what she gets is 125 g. Carleton

The latter has been creeping into British stores. Like Jim, I find it frustrating having to convert between prices per 100 grams and prices per kilogram, but unlike Jim, I need only multiply by 10, not by 16.

You've got some good background knowledge for a foundation for your views on that topic. I'm sure that you, as I do, find it frustrating to see one can of a product unit priced in cents per fluid ounce and another can unit priced in cents per pint.
