Calculate bra size and convert breast size

On this page, the calculator allows the user to calculate bra/breast/cup size in different countries by measuring the circumference of  bust as indicated on  picture on the right .  It can also convert bra size between different counties involving American, Canadian, Chinese, Italian, British, European, Japanese, Australian and New Zealand.

If under bust you entered is between 25-42, it uses inches as the default measurement unit. If under bust you entered is between 65-105, the default measurement unit is centimeter.
