I'm in Australia and I don't think I've ever heard of it (except maybe glossing over American recipes online). I've always measured butter in grams. The packaging often has markers so you can roughly estimate to the nearest 50g but that is it as far as I know. If anything I might have assumed it was something approximating these 50g slices.

Not so common in Canada either, it's usually measured in grams.
