110 French band sizes to US/UK band sizes

How to convert 110 FR/ES/BE to US/UK

US/UK = FR/ES/BE × 0.4 − 2

1. Take the value: 110 FR/ES/BE.
2. Multiply by 0.4: 110 × 0.4 = 44.
3. Subtract 2: 44 − 2 = 42.
4. So 110 FR/ES/BE = 42 US/UK.

Sizes come in steps of 2, so the nearest US/UK band size size is 42. 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.
