Rendered to 6 significant figures.
Formula
Formula
t = ct × 2e-7
Multiply any value in metric carats by 2e-7 to obtain the value in metric tonnes.
Worked example
Convert 1.00000e+6 ct to t.
- 01Start with 1.00000e+6 ct.
- 02Multiply by the conversion factor: 1.00000e+6 × 2e-7 = 0.2 t.
Result1.00000e+6 ct = 0.2 t

FAQ
What is the conversion factor from ct to t?
1 ct equals 2e-7 t. To convert, multiply the value in metric carats by 2e-7.
How do I convert 1 ct to t?
1 ct = 2e-7 t. For any value, multiply by 2e-7.
How do I convert t back to ct?
Divide by the same factor — or equivalently, multiply by 5000000. So 1 t = 5.00000e+6 ct.
When would I need to convert metric carat to metric tonne?
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).
