Science — not just boring physics equations. Apparently, science can also be used to determine some pretty wacky stuff, like which country's women have the largest breasts in the world. According to a new study published in the Journal of Female Health Sciences, American women have the biggest busts

Since bra sizes vary so wildly between countries (an American D-cup, for example, is labeled an F in Europe), researchers measured the volume of breast tissue in 11,682 women ages 28 - 30 from 108 different countries. 

"The study analysis revealed that there is a considerable variation in the breast tissue volume... of women depending on their country of birth," the researchers wrote. "For example women born in the U.S.A have by far larger breasts than women in any other country, while women born in Africa and Asia, particularly in the East Asian countries, have the smallest breast volumes."

The average American woman in this study was found to wear a D-cup (according to the American size system), whereas several countries in Africa and Asia had an average of an A-cup or smaller.

Researchers found that white American women have larger breasts than white women born in other countries in part due to the fact that American women's breasts tend to be rounder in shape. The rounder a breast is, the more volume it's likely to fill.
