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

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

metric tons = kilograms ÷ 1,000

The weight in metric tons is equal to the weight in kilograms divided by 1,000.

For example, here's how to convert 500 kilograms to metric tons using the formula above.
metric tons = (500 kg ÷ 1,000) = 0.5 t

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

What Is a Kilogram?

One kilogram is equal to 1,000 grams, 2.204623 pounds, or 1/1,000 of a metric ton.

The formal definition of the kilogram changed in 2019. One kilogram was previously equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.

The 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[1] It is equal to the mass of 1,000 cubic centimeters, or milliliters, of water.

The kilogram, or kilogramme, is the SI base unit for weight and is also a multiple of the gram. In the metric system, "kilo" is the prefix for thousands, or 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.

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.[2] 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.
