One size in, every system out
Most converters ask you to pick a "from" country and a "to" country separately. This one skips that step — enter your size once and see it converted across every major system in a single table, which is handy when you're comparing several stores from different regions at once.
Cup letters shift too: what's a UK "DD" is commonly a US "E" or "DDD" depending on the brand, and EU sizing often uses simple sequential letters. The table below reflects the most widely used convention for each system.
