What is the Cc and Cup Size after a surgery with 280 grams with diameter 116mm
A 280cc implant (grams and cc's are roughly equivalent for saline/silicone in this context) at 116mm diameter is a moderate-to-full profile implant, but there's no universal formula converting cc to cup size. The reason is cup size isn't standardized between bra brands, while cc is a precise volume measurement, so the two don't translate directly.
As a rough rule, 150-200cc often shifts a cup size by about one size, so 280cc might move someone up one to nearly two cup sizes, but this depends heavily on your starting breast volume, chest wall width, skin elasticity, and implant projection versus width. A wider chest wall with a 116mm diameter implant will look different on a narrow-framed patient than a broad one.
The rice-in-a-bag trick using an equivalent volume can give a rough sense of scale before surgery. For anything precise, an exam with your surgeon using sizers in your own chest wall and skin envelope will get you much closer to a real answer than any formula.
Clinical Context
Implant size alone doesn't determine bra cup size because cup measurements vary between brands and aren't standardized. What matters more is how the implant's width and projection fit your chest and existing breast tissue. Surgeons commonly use sizers during a consultation or in the operating room so you can see how a given volume looks on your own frame before finalizing the choice. This is why the same implant can look different on two people.
