The weight of breasts varies significantly depending on the size and cup. On average:

• A cup breasts weigh about 0.5 pounds (227 grams) each.
• B cup breasts weigh around 0.6 pounds (272 grams) each.
• C cup breasts weigh about 1 pound (453 grams) each.
• D cup breasts weigh about 1.5 pounds (680 grams) each.
• DD/E cup breasts weigh between 1.5 to 3 pounds (680 to 1360 grams) each.
• Larger cup sizes such as F and FF can weigh between 2 to 4 pounds (907 to 1814 grams) each.

These estimates assume an average band size around 34 and can vary due to factors like breast density and individual body composition.
