Why a cup can be 236.6, 240 or 250 ml

The US customary cup in measuring sets and US recipes is 236.6 ml. US nutrition labels round a cup to 240 ml for serving sizes, so a label's "1 cup" is 3.4 ml more than a measuring cup. Australian, New Zealand and Canadian recipes use a 250 ml metric cup, and older UK recipes a 284 ml imperial cup.
