How to Calculate Breast Implant Weight and Size

Updated on: April 1, 2019

If you're wondering how much breast implants weigh, use the information below to calculate the weight of various sizes of silicone and saline breast implants.

Below, you will find varying conversions, as well as how to calculate breast implant weight.

Please note: Silicone calculations and saline calculations are based upon measurements that I personally took by weighing 400cc silicone implant and a 400cc saline implant.

Silicone breast implant weight

1cc weighs 0.0375 oz.

To calculate the weight of silicone implants, see the directions below.

If you have two 300cc implants then: 300cc x 2 = 600cc total
600cc x 0.0375 = 22.5oz

22.5oz divided by 16oz = 1.40625 lbs. for both implants

Saline breast implant weight

If you have two 300cc saline implants then:

300cc x 2 = 600cc total

600cc divide by 29.574 (to convert to ounces) = 20.2880 ounces

20.5338 divided by 16 (ounces) = 1.268 lbs. for both implants
