The Question:

In diamond measurement, what is a carat?

The Answer:

One carat is equal to 200 milligrams. It's a useful measurement for dealing with very small things. Originally it was defined as the weight of a carob seed.

This should not be confused with a caret, which is the ^ symbol, used to indicate an insertion.
