Working backwards from a size
Most calculators go from measurements to a size. This one runs the other direction — enter a bra size you already know, and see roughly what bust measurement it implies. That's useful for buying a gift, comparing a size someone mentioned, or sanity-checking a size against your own measurements.
Since the same size can be cut slightly differently between brands, treat the result as a useful estimate rather than an exact figure.

It's a solid estimate, but actual bust measurement can vary slightly by brand due to differences in cup cut and pattern.
