Convert metric carats (ct) to grams (g).
Factor1 ct = 0.2 g
Converter
ct
Accepts numbers or expressions, e.g. 150 + 14.7
Result
g
Rendered to 6 significant figures.
Formula
Formula
g = ct × 0.2
Multiply any value in metric carats by 0.2 to obtain the value in grams.
Worked example
Convert 5 ct to g.
- 01Start with 5 ct.
- 02Multiply by the conversion factor: 5 × 0.2 = 1 g.
Result5 ct = 1 g

FAQ
What is the conversion factor from ct to g?
1 ct equals 0.2 g. To convert, multiply the value in metric carats by 0.2.
How do I convert 1 ct to g?
1 ct = 0.2 g. For any value, multiply by 0.2.
How do I convert g back to ct?
Divide by the same factor — or equivalently, multiply by 5. So 1 g = 5 ct.
When would I need to convert metric carat to gram?
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).
