Timber sometimes gets called 2x4 even though it's 50x100, but that seems less common now.
Oddly just about everyone still uses feet and inches for their height. I hear kilos more and more often for weight, I don't think I've ever heard cm for height in the UK.
Returned milk is (you know, in dem bottles). But milk you buy in the store is 1L, 2L, etc.

True. Probably because of the recognition of the 6' centering measurement. People know that if you're 6', that's kind of the cut-off for what is referred to as 'tall enough'. Over that, you're generally 'tall'. Under that, and you're average height.

Pretty much the only conversions people ever do are between inches and feet when talking about height.
