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