Mathematical equations for boobies

The average breast weighs about 0.5 kilograms (1.1 lb).Each breast contributes to about 4–5% of the body fat.

The density of fatty tissue is more or less equal to 0.9 for all women. The volume of a woman's individual breasts can vary. Bra designers can give it the shape of a hemisphere or an hemi-spheriod by fitting it in a cup. If the bust is considered essentially a half-sphere, its volume V is determined by the following formula.

where D is the diameter of the sphere, and r is its radius.

If the breast is shaped more like a spheroid, the designer might use a formula like the following:

Where Db equals diameter of the hemi-spheroid's base and h equals the height of the spheroid. Other formulas can be derived as needed to design bras for differently shaped breasts. All of these formulas assume that breasts conform to a mathematical model.

Cups give a hemi sperical shape to breasts and underwires give shape to cups. So the curvature radius of the underwire is the key parameter to determine volume and weight of the breast. The same underwire are used for the cup of size 36A, 34B, 32C, 30D and etc... so those cup have the same volume. The reference number of underwire size are based on B cup bra, for example underwire size 32 is for 32B cup (and 34A, 30C...). An underwire size 30 with has a curvature diameter of 3 inch 5/6 ≈ 9.7 cm and this diameter increase of ⅓ inch ≈ 0.847 cm by size

But they are all delightful aren't they?

Now you mention it my maths teacher had nice tits.

If they would have used boobs in my math classes I might have paid more attention.

If the hemisphere theory held true, than when a woman scrunched her titties together, they would form a sphere, and I can tell you from first hand experience that is not the case, though I would be happy to test the theory on larger cross section of the female population.

Girls, start lining up on my left please.....

Boy does take the fun out of boobs. Rather just look and think about tounge whipping the nipple. But I do believe somebody had to figure it out. Heard it said Howard Hughs has a go at design while he was in his hayday. Can't think of his main project. She was in a movie he made about Billy the Kid and Pat Garret.

Where did you get that information?

Someone has way to much time on his hands and needs redirection by a strict mommy.

So the reasons I can't find bras that fit the way I like them is because of math? I guess that is as reasonable an explanation as I have got anywhere. So I'm still wondering why the Victoria's Secret bra is a 36C and the Bali of the same style is a 34C. Is a bra designed to flatter the men who look at us or the sizing to flatter the wearer?

I'd be just as happy being a volumetric consultant on the subject. 😃

As a civil engineer I often calculate vessel capacities and if Skybear ever needs a job he can send me his resume. The nice thing about boobies is that are pliable and can assume within reason various shapes. Now shape preferences come and go because I can remember the sweater bras that were designed so you did not see either nipple or bra seams. Underwires hold breasts entirely different than natural cup bras and I happen to be especially fond of the perky or tits up look. Then again years ago there were the bras that gave women that "pointy knockers" look. I've been a boob man like forever and my wife just rolls her eyes. Thanks for posting this thread.

I think Victoria's Secret does vanity sizing.

They sure do!

Bigger size names for breasts/bras, smaller size names for other clothes like panties, lingerie, sport wear.

Big tits and small slim bodies is where it's at!

They have to make the customers happy.

Considering their stuff doesn't fit me, VS doesn't keep me happy... so I don't shop there. But I digress from the topic at hand...

With or without doing the math on this, I prefer a push up underwire brassiere or a really good sports bra per what I am doing.

I long ago nicknamed my brassiere's "over the shoulder boulder holders".

This brings to mind this classic scene from the movie Beaches...ENJOY! 😁

Great movie, still one of my all time favorites.

Hmmm, I'm curious where this came from, too.

I recently saw a breast specialist due to some pain and tenderness that we can't quite figure out. Her assistant weighed and measured each breast and based on those measurements did a density analysis. One was 2.8lbs, the other is 3.2lbs. I usually wear either a 36C or 36D (depending on cut and brand), so I'm surprised by the OP's note that they are about a pound.

It's the relentless onward march of evolution: we're all getting larger. The OP's note dates back to 2012.

Mother always said, and she toted quite a "load around" that woman should go to, and I forget what she called it, but she claimed it was the only way of getting a bra that fit and did what it was supposed to do. They would measure and fiT AND SUCH So you weren't trying to stuff 10lbs of taters into a 5 lb bag.

Musicman5360 -- Do you mean a corsetiere--person who makes bras and girdles?

Maybe the problem is "new math".

No susie, that doesn't sound quiet right. but mother is gone 15 years and the memory fades!

Admittedly i do like figures...but prefer to enjoy them

We have a brand here called HESTIA - also jokingly known as "Holds Every Size Tit In Australia"...go figure...mathematics !!

I think Victoria's Secret does vanity sizing.

Wouldn't vanity sizing, done right, apply more to the cup size than chest diameter? I'm not aware of too many women bragging about how broad their chests are, or of many male bodybuilders buying bras.

I'm a 36 D and oh so saggy. You never mentioned any breast binding facts! 😉
