34 US/UK band sizes to EU band sizes

How to convert 34 US/UK to EU

EU = US/UK × 2.5 − 10

1. Take the value: 34 US/UK.
2. Multiply by 2.5: 34 × 2.5 = 85.
3. Subtract 10: 85 − 10 = 75.
4. So 34 US/UK = 75 EU.

Sizes come in steps of 5, so the nearest EU band size size is 75. 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.
