How to Convert Grams to Metric Tons

To convert a gram measurement to a metric ton measurement, divide the weight by the conversion ratio.

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 grams divided by 1,000,000.

For example, here's how to convert 500,000 grams to metric tons using the formula above.
500,000 g = (500,000 ÷ 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.


A gram is the mass/weight equal to 1/1,000 of a kilogram and is roughly equivalent to the mass of one cubic centimeter of water.

The gram, or gramme, is an SI unit of weight in the metric system. Grams can be abbreviated as g; for example, 1 gram can be written as 1 g.

Metric Tons (Tonnes)

One tonne is equal to 1,000 kilograms or 2,204.6 pounds, and is used throughout the world as a unit of mass/weight.[1] One tonne is also equal to 1 megagram. The metric ton should not be confused with short tons, used primarily in the US, or long tons, used primarily in the UK.

The metric ton is an SI accepted unit for weight for use with the metric system. A metric ton is sometimes also referred to as a tonne. Metric tons can be abbreviated as t, and are also sometimes abbreviated as T, Te, or MT. For example, 1 metric ton can be written as 1 t, 1 T, 1 Te, or 1 MT.

In the US the unit is referred to as the metric ton, while the rest of the world refers to it as the tonne. Most often it's still pronounced as tun, but it is sometimes pronounced tunny.
