FAQ
What is the conversion factor from ct to mg?
1 ct equals 200 mg. To convert, multiply the value in metric carats by 200.
How do I convert 1 ct to mg?
1 ct = 200 mg. For any value, multiply by 200.
How do I convert mg back to ct?
Divide by the same factor — or equivalently, multiply by 0.005. So 1 mg = 0.005 ct.
When would I need to convert metric carat to milligram?
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).
