I agree with Bruce, Google is a good place to start. I found the following:Diamond weights are measured in carats. One carat equals 1/142nd of an ounce, or 1/5th of a gram. In other words... there are 142 carats in 1 ounce and 5 carats in 1 gram.
Google is your friend and mine.I typed in :carets in a ozand got:1 ounce = 141.747616 caratsandhow many troy oz in a poundand got1 pound = 14.5833333 troy ozyou get the idea. Google has a calculator that makes this possible.
