Saline implants weight approximately 1 g per cc (or ml) of saline solution. This translates into about .6 pounds for a 300 cc saline implant. Silicone is slightly more dense than water. A 300 cc implant will weight about .7 pounds. Best Wishes, Neil Zemmel, MD Richmond, VA
Breast implant size is measured in cubic centimeters, or "cc's", not bra cup size. Each cc weighs 1 gram.
