It is, and everything is required to be sold in metric units. Except for things like pipe fittings and screw sizes, but even those have to show the metric somewhere.

There's an effort to switch car efficiency from mpg (higher is better) to "l/100km" (smaller is better), because the latter has more intuitive scaling as well as being properly metric.

There were definitely people complaining about the price hike when the currency changed, but that was back in 1971 so it's only boomers who'll bring it up.

Some pipes are in imperial units in Italy too. For example, from my memories of few days ago at a store: we have metric series of rigid PVC water pipes (32 mm, 40 mm, 50 mm) and imperial series for the flexible ones used for watering plants and grass. I remember sizes of 1/2" 3/4" 5/8" 1" 1 1/4". But there are also metric ones that more or less can fit with some of the imperial ones. Of course there are two series of adapters, hoses, etc.

Gas pipes are imperial. I think they never changed to metric because of safety concerns or because the number of meters sold is lower than water pipes (gas pipes last forever) and it's not worth splitting the market in two. But it's just my suppositions.

I can see bearing a grudge for 50 years over that one, though.
