Formula
Formula
µg = ct × 200000
Multiply any value in metric carats by 200000 to obtain the value in micrograms.
Worked example
Convert 1 ct to µg.
- 01Start with 1 ct.
- 02Multiply by the conversion factor: 1 × 200000 = 200000 µg.
Result1 ct = 200000 µg

FAQ
What is the conversion factor from ct to µg?
1 ct equals 200000 µg. To convert, multiply the value in metric carats by 200000.
How do I convert 1 ct to µg?
1 ct = 200000 µg. For any value, multiply by 200000.
How do I convert µg back to ct?
Divide by the same factor — or equivalently, multiply by 5e-6. So 1 µg = 5e-6 ct.
When would I need to convert metric carat to microgram?
Mass conversions appear in material balances, reagent dosing, and reconciling vendor specifications across imperial/metric systems.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
