How to Convert Carats to Metric Tons

To convert a measurement in carats to a measurement in metric tons, divide the weight by the following conversion ratio: 5,000,000 carats/metric ton.

Since one metric ton is equal to 5,000,000 carats, you can use this simple formula to convert:

metric tons = carats ÷ 5,000,000

The weight in metric tons is equal to the weight in carats divided by 5,000,000.

For example, here's how to convert 5,000,000 carats to metric tons using the formula above.
metric tons = (5,000,000 ct ÷ 5,000,000) = 1 t

Carats and metric tons are both units used to measure weight. Keep reading to learn more about each unit of measure.
