How to Convert Grams to Metric Tons

Scales are used to measure weight

To convert a gram measurement to a metric ton measurement, multiply the weight by the conversion ratio. One gram is equal to 1.0E-6 metric tons, so use this simple formula to convert:

metric tons = grams × 1.0E-6

The weight in metric tons is equal to the grams multiplied by 1.0E-6.

For example, here's how to convert 5 grams to metric tons using the formula above.
5 g = (5 × 1.0E-6) = 5.0E-6 t

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.
