Carat (ct). The metric carat is 200 milligrams, the unit for diamonds and gemstones.
Microgram (µg). A microgram is one millionth of a gram, used for vitamins, medicines and trace amounts.
There are 200,000 micrograms in one carat.
Multiply the number of carats by 200,000. For example, 10 carats equal 2,000,000 micrograms.
One microgram equals 5 × 10⁻⁶ carats.
2,400,000 micrograms. Other common values: 5 carats = 1,000,000 micrograms and 100 carats = 20,000,000 micrograms.
