Rendered to 6 significant figures.
Formula
Formula
ct = µg × 5e-6
Multiply any value in micrograms by 5e-6 to obtain the value in metric carats.
Worked example
Convert 200000 µg to ct.
- 01Start with 200000 µg.
- 02Multiply by the conversion factor: 200000 × 5e-6 = 1 ct.
Result200000 µg = 1 ct

FAQ
What is the conversion factor from µg to ct?
1 µg equals 5e-6 ct. To convert, multiply the value in micrograms by 5e-6.
How do I convert 1 µg to ct?
1 µg = 5e-6 ct. For any value, multiply by 5e-6.
How do I convert ct back to µg?
Divide by the same factor — or equivalently, multiply by 200000. So 1 ct = 200000 µg.
When would I need to convert microgram to metric carat?
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).
