# How Much Does a Silimed Breast Implant Weigh?

I had Silimed cohesive gel textured high profile 350cc implants placed in March 2011. I am wondering how much does one implant weigh in US measurements ( pounds & ounces ) ?

### Breast implant weight

The weight of a breast implant is dependent on its size. In general, each cc is equal to one gram. So, a 350cc implant weighs about 350 grams. There are 454 grams in a pound, so a 350cc implant weighs 350/454= 0.78 lbs; or just over 3/4 of a pound.

### How much do breast implants weigh?

Dear Just5kidz,  A 350cc cohesive silicone gel-filled implant should weight approximately 3/4 of a pound.   Doing the math, two implants should add about 1.5lbs to your weight.

### Silicone weighs less than water

Hello, Water weighs about 7 lbs per gallon. Implant size is measured in millileters. Silicone weighs slightly less. The weight of your implant depends on the size primarily and then whether its saline or silicone secondarily. All the best. Dr Repta

### 350cc implant weighs 0.77 lbs.

The calculation is as follows: 350cc = 350 grams.

454 grams = 1 pound.

Thus, 350/454 = 0.77 pounds. two implants will weigh 1.54 pounds.

Remember, after surgery there is much retained fluid and swelling, which takes several weeks to be eliminated from your body. If you stand on a digital scale the morning of surgery, and again the night after surgery, you can gain as much as 5-7 pounds, most of which is swelling (fluid) weight.
