Carat to micrograms Conversion
1 carat (CD) is equal to 200000 micrograms (μg).
1 CD = 200000 μg
or
1 μg = 0.000005 CD
Formula
To convert a mass from carat (CD) to micrograms (μg), multiply the mass in carat by 200000
m(μg) = m(CD) × 200000
Examples:
Convert 50 carat to micrograms:
m(μg) = 50CD × 200000 = 10000000 μg
