What this converter does
Bra sizing differs by country: a US 34DD is a UK 34DD but an EU 75E. This converter takes a size in any one of six systems — US, UK, EU, French, Australian or Japanese — and gives you the equivalent in all the others. Band numbers and cup letters are converted separately, because they do not scale the same way.
