Most milk bottles I've seen list volumes in both litres and pints, which solves the labelling problem fairly well in practice. You can usually work the difference between 1/2/4/6 pint bottles out from shape and size alone. I've seen 2 litre bottles in the past, but they're pretty rare.
The butter I have to hand is in 250g blocks, so is entirely metric-based for now.
