The tonne (non-preferred SI derived unit; SI symbol: t), commonly referred to as the metric ton in the United States, is a non-SI metric unit of mass equal to 1,000 kilograms; or one megagram (Mg); it is equivalent to approximately 2,204.6 pounds, 1.10 short tons (US) or 0.984 long tons (imperial). Although not part of the SI per se, the tonne is "accepted for use with" SI units and prefixes by the International Committee for Weights and Measures, along with several other units like the bar, litre and day.
| 1 tonnes ≡ 5000000 carats | 11 tonnes ≡ 55000000 carats |
| 2.5 tonnes ≡ 12500000 carats | 12.5 tonnes ≡ 62500000 carats |
| 4 tonnes ≡ 20000000 carats | 14 tonnes ≡ 70000000 carats |
| 5.5 tonnes ≡ 27500000 carats | 15.5 tonnes ≡ 77500000 carats |
| 7 tonnes ≡ 35000000 carats | 17 tonnes ≡ 85000000 carats |
| 8.5 tonnes ≡ 42500000 carats | 18.5 tonnes ≡ 92500000 carats |
| 10 tonnes ≡ 50000000 carats | 20 tonnes ≡ 100000000 carats |
| 1 carats ≡ 2.0 × 10-7 tonnes |
