About converting Carats to Metric Tons
Carats (ct) and Metric Tons (t) are both units of weight & mass, so converting between them is a single multiplication: multiply your Carats figure by 0.0000002. Ten Carats comes to 0.000002 Metric Tons, and a hundred works out at 0.00002 Metric Tons.
Rule of thumb: going from Carats to Metric Tons divides, so the figure always shrinks — it takes about 5,000,000 Carats to make a single Metric Ton. If your answer came out bigger, you have the conversion the wrong way round.
What is a Carat?
The metric carat is 0.2 grams exactly, standardised early in the twentieth century to replace a tangle of local carats that differed from one gem market to the next. Its name is traditionally traced to the carob seed, once used as a counterweight for small valuables. The trap is the near-identical karat, which is not a mass at all — it measures gold purity in twenty-fourths, so 18-karat gold is eighteen parts gold to six of other metal. Jewellers also split the carat into 100 points, which is why a "fifty-point" diamond is simply half a carat.
What is a Metric Ton?
A metric ton — spelled tonne almost everywhere outside the United States — is 1,000 kilograms. It is not strictly an SI unit, though SI accepts it for use alongside them; the coherent name would be the megagram, which essentially nobody says out loud. The real hazard is the bare word "ton", because a US short ton of 2,000 pounds and a British long ton of 2,240 pounds are different quantities again, and all three are close enough that a careless figure can pass unchallenged. It is the unit of freight, steel, harvests and carbon dioxide emissions.
To put both in perspective: a typical engagement-ring diamond weighs about one carat, while a small car weighs about 1.5 metric tons.
