I can imagine the chagrin. Americans tend to measure a lot in cups, tablespoons, and teaspoons. Anyone who uses recipes from all over the world would be well advised to simply get a set of cups (get one that stacks the 1, ¾, ½, ⅓, ¼ measures etc. as a Matroska doll) and a ring of measuring spoons.

Not at all — just the US cups will do. Modern UK recipes tend to use tablespoons and teaspoons, but not cups.
