1 and 85B indicate that the lower bust is 85cm, and the cup is B, that is, the difference between the upper bust and the lower bust is12.5cm. It can be inferred that the upper bust is 97.5cm. The calculation formula of the cup is: cup size = upper bust size-lower bust size is every 2.5cm, and the minimum size is 7.5cm, and A is/kloc.

2. Underwear sizes generally consist of numbers and letters, such as 32/70A and 36/80C. The data of three States were measured: the upper bust is generally upright, 45 and 90; Add up the three data, and then √2 to get the average value of upper bust. For example: upright is 90, 45 is 9 1, 90 is 92; (90+91+92) ÷ 2 = 9191is the average upper bust.
