It is every country in the world (including the US, officially, in 1975) discarding their entire history of traditional units, in favour of globally standardised weights and measures. Don't you think French chefs miss their chopines and boisseaux ?
It's every country in the world, vs the holdouts of the USA, Liberia and Burma.
There are plenty of other troubles with making universal recipes! They often rely on ingredients that one country takes for granted while they're an expensive specialty in your country; sometimes they're the key ingredient that make the recipe work, other times it's just what they had to hand, and you should substitute with local equivalent. Or when a chef says "435g of beans" that's because their country customarily sells tins with 435g of beans in them, and they just use one customary tin and base the rest of the ingredients around that volume. If your tins are 400g or 500g, what you really need is the recipe localised to match your customary supplies.
We'll never get away from the customary practises of every country, but we could at least be precise when writing them down?
