The strict answer is that that a 15 carat stone weighs 15 carats. You probably want to know how big the stone looks. Use the link, below, to get a visual idea of about how large a stone might look depending on its carat weight, and its cut. If the 15 carat stone is a brilliant cut, the stone would be about 16.3 MM across at the girdle.

Cubic Zircons are often meant to mimic diamonds. Since CZs have a more dense specific gravity than diamond -- Wikipedia indicates at least 1.6 times that of diamond. This means that carat weight would be less for the CZ to equal the carat weight of a diamond, both being equal in size. Using the number 15 indicates that you're looking for a large stone. In this case, you may want to go by measurement and not by carat weight. For example, a 15 carat, round diamond measures about 16.3mm across the diameter of the girdle. Presenting the data in reverse, a 15 carat CZ will weigh 1.6 times more than a 15 carat diamond: so the equivalent size diamond in weight will be less than 15 carats. Determining the carat weight of a CZ which is 16.3mm across at the girdle can be made by a jeweler who can weigh the CZ stone and give you its equivalent carat weight.
You can calculate the total carat weight by adding the individual carat weight of each stone. Without a carat weight of each of your 15 stones, it is not possible to devise a sum total carat weight.
