How to Convert Grams to Metric Tons

To convert a measurement in grams to a measurement in metric tons, divide the weight by the following conversion ratio: 1,000,000 grams/metric ton.

Since one metric ton is equal to 1,000,000 grams, you can use this simple formula to convert:

metric tons = grams ÷ 1,000,000

The weight in metric tons is equal to the weight in grams divided by 1,000,000.

For example, here's how to convert 500,000 grams to metric tons using the formula above.
metric tons = (500,000 g ÷ 1,000,000) = 0.5 t

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