48 US/UK band sizes to Italian band sizes

How to convert 48 US/UK to IT

IT = US/UK × 0.5 − 15

1. Take the value: 48 US/UK.
2. Multiply by 0.5: 48 × 0.5 = 24.
3. Subtract 15: 24 − 15 = 9.
4. So 48 US/UK = 9 IT.

Sizes come in steps of 1, so the nearest Italian band size size is 9. This converts the band (number) part of a bra size only. Cup letters also differ between systems (for example, US DDD is UK E), so check the brand's chart for cups.
