How to Convert Metric Tons to Milligrams

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

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 weight in metric tons multiplied by 1,000,000,000.

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

What Is a Metric Ton (Tonne)?

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.
