Here is how I would recomend calculating size and mass of breasts.

Going of the use of a gallon as a standard of measure, we see it equals a volume of 3785.412 cubic centimeters, or 231 cubic inches. Now, if we look at each breast as half a sphere, than together, two breasts having a weight of 8 lbs will have a volume of 231 cubic inches. Volume = 4/3 Pi times Raduis cubed. Therefor it follows that the cube root of ((3/4*231)/pi)= the radius of the sphere. This amounts to a raduis of 3.8 in. Cut that sphere in half and place it on a womans chest, and you have two breasts that stick out approx. 3.8 inches from her chest, not counting the nipple.

Cup size is calculated by the circumfrance of the breasts at the widest point, minus the circumfrance of the underbreast. Using a willing voulenteer, I have generated a baseline underbreast measure of 33 in. The circumfrance of the breastline is the sum of 1/2 the circumfrance of each breast, or 1 circle with a radius of 3.8 in in this case. So without counting the circumfrance of the back, the circumfrance of the breasts=2*pi*r=24 in. Using my same willing voulenteer, I give a ballpark measure of a womans back at 20 in. So add 24 to 20 and you'd have bustline measure of 44 in. 44 minus 33=11in= an H cup size.

Therefore, a woman with H cups would have breasts which have a combined weight of 8 lbs.

as potatodave noted, if the volume or mass of an object is altered by any factor, the other will be altered by the same factor. So, to calculate the weight of breasts of any size, look at the following formula.

Cup size=Bustline measure-33in(underbust of average woman). Cup size translates as (0in=A, 1in=B, 2in=C etc)

Bustline=Cupsize (in inches)+33in = 2*pi*r of the breasts+20in (The distance around the back of a fairly average woman).

r= (Cupsize+33in-20in)/2pi

4/3*pi*r^3=volume of breasts.

Volume of breasts/231=Factor ratio to 1 gallon.

Factor ratio*8lbs=weight of breasts.

Ta da

Note: You may substitute in different underbust measures and back measures if you'd like. The formula works regardless.
