Cc is a (metric) measure of volume; grams are a (metric) measure of weight. 1cc = 1gram

This can be confusing if you are not used to metrics, but 1cc (cubic centimeter) is the same as 1ml (milliliter) and both weigh 1 gram. Breast implants are measured in volume (cc), but since these are metric measurements, 295cc = 295grams.

Perhaps another example will help you understand why cc and grams are NOT the same, but can be used interchangeably. 1 gallon (a US measure of volume) weighs about 8 pounds (US measure of weight). You wouldn't say you were going to the store to buy 8 pounds of milk, but if that "equivalence" was common and intuitive, like 1cc = 1gram, then you could think about weight and volume in a similar fashion.

I hope this helps. BTW, 295grams is just over 1/2 pound (454grams per pound). Best wishes!

Grams versus cc

In the metric system, 1 gram of water takes up 1 cc of volume ( under standard conditions).  So, yes - a 400 cc saline implant would weigh 400 grams for the saline + the weight of the implant's shell.

So, with the exception of the implant shell, these are pretty much interchangeable.


All the best!

CCs and Grams are almost equivalent when speaking about implant size(weight).  CC is a measure of volume and Grams is a measure of weight in the metric system.

Grams vs. CCs When It Comes To Breast Implants - Are They The Same Thing?

Most implant manufacturers and most plastic surgeons refer to the volume of a breast implant in ccs (which means cubic centimeters).  Grams are a measurement of weight.  With reference to weight, one gram of water takes up one cubic centimeter in the metric system.  For all intent and purposes, a 500 cc implant equals 500 grams.

With reference to silicone implants, one gram does not equal exactly one cubic centimeter, but it is close enough.  Therefore, when your surgeon refers to a 295 gram implant, it is effectively the same thing as a 295 cc implant. 

Breast implants in the US labeled according the volume

Here in the US breast implants are labeled by volume or cc's. The exception is the gummy bear which is measured in grams. The weight and volume numbers are so close that they can be considered 'equivalent' in practical use. We would consider the 295cc and 295 gm the same.

Cc vs. grams

Thank you for your question.  Breast implants are manufactured by volume, not weight.  They are often noted as a certain volume in cc or ml (milliliters).  A 295cc implant is the same as a 295ml implant.  Hope that helps.

Volume vs. weight and breast implants

First of all, all the implants are marketed by volume, not weight. For saline, one cc of volume weighs one gram.  For silicone gel, that is almost correct, though the one cc of gel weighs weighs slightly less than one gram (0.98 grams to be exact)

A 400 cc gel implant has 400 cc of silicone gel. A 400 cc saline implant if filled to that amount also has 400 cc.  The entire implant will, however, weigh a bit more, because the shell has some weight also, averaging about 20 grams. 

A 295 cc implant of saline or silicone would be precisely the same as a 295 gram implant not counting the shell weight. If a gross weight of 295 cc is important to you, a 275 cc implant will weigh closest to your goal. 

Best wishes
