60G bra size
A 60G bra is cut for an underbust of 57.5–62.5 cm and a bust of 84–86 cm. Below it is the same size as every other system prints it, and the sister sizes that hold the same cup.

Where each notation comes from
What each notation means — why the British band reads 34 and the Italian reads 2 — is set out system by system on the bra size page.

Nothing here is looked up in a table of equivalents: band and cup are computed once from the metric ladder, then printed in each system’s own letters (formula version 2).

Where these numbers come from
The band is the underbust rounded to the nearest five centimeters, so 57.5–62.5 cm all round to 60. The cup is how far the bust exceeds that band’s nominal value: 24–26 cm gives this letter, at two centimeters per letter starting at ten. Add them and you get a bust of 84–86 cm.
The cup is measured against the nominal 60, not against the tape. That is what every published chart does, and it is why an underbust at the bottom of this band and one at the top get the same letter despite five centimeters between them. Near a band edge, try the sister size too.
In inches, 60G is an underbust of 22.6–24.6" and a bust of 33.1–33.9". Note that the UK and US band number is not that measurement: 60 cm is 22.6–24.6", and the band is called 28F because the English notation adds four inches.
Same cup as 60G, different band
One band up is one letter down, because the cup is measured over the band — which makes 65F the same volume as 60G. In a shop the printed size that fits is routinely not the one the tape said, so these are worth trying on.
One step away
60F, 60H, 65G — a letter either side of 60G on this band, and this letter on the neighbouring bands.
