How Much Do Saline C Cup Implants Weigh?

A 1000 cc saline implant will weigh 2.2 pounds or 35 ounces. If you do the math you can figure out exactly how much your implants will weigh. Silicone will weigh slightly less. The average A to C cup requires about a 350 cc implant which is roughly the same as a 12 oz soda to give you a reference point.

Saline implant volumes are sized on the metric system, in cc's, which means cubic centimeters. There are 1000 cc's in a liter, which weighs 1 kilogram by definition, which is 2.2 lbs. So a 450 cc implant is about 1 pound. Silicone implants are slightly lighter.

To tell you what a cup size weighs is very difficult.  First the exact cup size varies from bra to bra.  Also what volume are you starting with? To tell you the weight of an implant is easy.  A 300 cc volume implant will weigh 300 gms or about 0.66 lbs.

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.

Breast implant size is measured in cubic centimeters, or "cc's", not bra cup size. Each cc weighs 1 gram.
