Specifically: Megagram is 1000000 gram units, and a metric carat is exactly 200 milligrams.
Formula
carats = megagrams × 5000000
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram equals 1000 base units, and 1 carat equals 0.0002 base units, so dividing one by the other gives the direct megagram-to-carat factor of 5000000.
