How to convert micrograms to carats

ct = µg ÷ 200,000

To convert micrograms to carats, divide the number of micrograms by 200,000.

Example: 18 µg to ct

Start with the value in micrograms: 18 µg.
Divide by 200,000: 18 ÷ 200,000 = 0.00009.
Result: 18 micrograms = 0.00009 carats.

Going the other way, 1 carat = 200,000 micrograms, so to convert carats back to micrograms you multiply by the same number. See carats to micrograms.
