How do you convert kg to metric tons?

Divide the kilograms by 1,000, because one metric ton is exactly 1,000 kg. For example, 3,200 kg ÷ 1,000 = 3.2 metric tons. To reverse it, multiply the metric tons by 1,000.

How many kg is equal to 1 metric ton?

One metric ton equals exactly 1,000 kilograms. This is fixed by the SI definition, so there is no rounding — unlike the US short ton (907.18474 kg) or UK long ton (1,016.0469 kg).

Is a metric ton the same as a tonne?

Yes. 'Metric ton' and 'tonne' are two names for the same unit of 1,000 kilograms, symbol t. British and international English usually write 'tonne'; American English writes 'metric ton' to distinguish it from the US short ton.

How do I convert metric tons back to kg?

Multiply the number of metric tons by 1,000. For example, 4.5 metric tons × 1,000 = 4,500 kg. Just flip the direction toggle on the calculator above to do it automatically.

The short answer

How do you convert kilograms to metric tons?

To convert kilograms to metric tons, divide the number of kilograms by 1,000, because one metric ton (also spelled tonne, symbol t) is defined as exactly 1,000 kilograms. So 1,500 kg ÷ 1,000 = 1.5 metric tons, and 2,000 kg = 2 t. This is the only ton type with an exact, round conversion, which is why it is the global standard used in international trade, shipping and science. The metric ton is distinct from the two customary tons: a US short ton is 907.18474 kg and a UK long ton is 1,016.0469 kg, both smaller or larger than 1,000 kg. If a figure simply says 'ton' with no country context, it is almost always a metric ton outside the United States. Enter any kilogram amount above and the exact metric-ton value appears as you type.

Formula & method

How is it calculated?

t = kg ÷ 1,000

Kilograms to metric tons — divide by the exact SI constant.

t: Metric tons (tonnes) — the result
kg: Kilograms — the amount you are converting
1,000: Kilograms in one metric ton (exact, by SI definition)

Step by step

1
Take the mass in kilograms.
2
Divide it by 1,000.
3
The result is the mass in metric tons. To go the other way, multiply tons by 1,000.

Examples

Worked examples

Real numbers, worked all the way through — so you can sanity-check the calculator against your own figures.

A shipment weighs 1,500 kg on the manifest.

Mass: 1,500 kg

Metric tons: 1.5 t
Formula: 1,500 ÷ 1,000

Dividing by 1,000 shifts the decimal three places — 1,500 kg is exactly 1.5 metric tons.

A grain silo holds 25,000 kg of wheat.

Mass: 25,000 kg

Metric tons: 25 t
Formula: 25,000 ÷ 1,000

25,000 kg is 25 metric tons — the round relationship is why metric is the trade standard.

Methodology

Accuracy & assumptions

Every calculator makes assumptions. Here are ours, stated plainly, so you know exactly what the numbers do and do not account for.

One metric ton is exactly 1,000 kg by SI definition — this conversion has no rounding.
'Metric ton', 'tonne' and the symbol 't' all mean the same 1,000 kg unit.
This is not the US short ton (907.18474 kg) or the UK long ton (1,016.0469 kg).

Conventions follow the SI (International System of Units), maintained by the BIPM, with US customary values published by NIST. Every result is derived from the exact kilogram-to-ton constants, so figures match the definitions rather than rounded approximations.

Details

What are the key details?

Scannable facts worth knowing before you convert or compare a ton figure.

The metric ton is the standard unit of mass for freight, commodities and bulk cargo in almost every country except the US.
It is a decimal multiple of the kilogram, so conversions are exact and never need a rounded factor.
Megagram (Mg) is the strict SI name for the same quantity, though 'tonne' is used in practice.
Outside the United States, an unqualified 'ton' should be read as a metric ton.
