How to Convert Milligrams to Metric Tons

Scales are used to measure weight

To convert a milligram measurement to a metric ton measurement, multiply the weight by the conversion ratio. One milligram is equal to 1.0E-9 metric tons, so use this simple formula to convert:

metric tons = milligrams × 1.0E-9

The weight in metric tons is equal to the milligrams multiplied by 1.0E-9.

For example, here's how to convert 5 milligrams to metric tons using the formula above.
5 mg = (5 × 1.0E-9) = 5.0E-9 t

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

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.

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. 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.
