How to Convert Metric Tons to Milligrams

To convert a metric ton measurement to a milligram measurement, multiply the weight by the conversion ratio.

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

milligrams = metric tons × 1,000,000,000

The weight in milligrams is equal to the metric tons multiplied by 1,000,000,000.

For example, here's how to convert 5 metric tons to milligrams using the formula above.
5 t = (5 × 1,000,000,000) = 5,000,000,000 mg

How Many Milligrams Are in a Metric Ton?

There are 1,000,000,000 milligrams in a metric ton, which is why we use this value in the formula above.

1 t = 1,000,000,000 mg

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

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.


The milligram is the mass equal to 1/1,000 of a gram, or 0.0154 grains.

The milligram, or milligramme, is an SI unit of weight in the metric system. In the metric system, "milli" is the prefix for 10-3. Milligrams can be abbreviated as mg; for example, 1 milligram can be written as 1 mg.
