Carats and millimeters do not correlate directly.
If, however, your question is about a gemstone cut as a round brilliant gem, it may weigh between .40 and .50 carats or 40/100ths or 50/100ths of a carat.
Take your gemstone to a jeweler whom you trust and ask that the diamond be removed from its setting and weighed. That is the only way to know the exact weight of any gemstone.
