Convert tonnes to kg
Convert tonnes to kg instantly. 1 t = 1,000 kg. Formula, worked examples and a quick reference table.
Last updated
One metric ton equals 1,000 kilograms. To convert any number of metric tons to kilograms, multiply by 1,000.
The converter above works in both directions and updates as you type. Below you will find the formula, a worked example and a reference table of common values.
Weight and mass conversions matter most in three places: shipping, where a rate band can turn on a single kilogram; cooking, where recipes cross between metric grams and imperial ounces; and personal weight, where Britain and Ireland use stones, the United States uses pounds, and everywhere else uses kilograms. Strictly these are mass units rather than weight units, and the distinction only bites in physics, where weight is a force measured in newtons.
tonnes to kg formula
To go the other way, use metric ton = kilogram ÷ 1,000.
About these units
The tonne is 1,000 kilograms — close enough to the imperial long ton to be confused with it, and about 10% larger than the US short ton of 2,000 pounds.
Since 2019 the kilogram has been defined by the Planck constant rather than a metal cylinder in Paris, making it reproducible in any properly equipped laboratory.
Metric Ton is also written tonne, tonnes, metric tonne, ton, tons and mt. Kilogram is also written kilogramme, kilogrammes, kilograms, kilos, kilo and kgs.

Frequently asked questions
How many kilograms are in a metric ton? +
There are 1,000 kilograms in one metric ton.
What is 10 t in kg? +
10 t equals 10,000 kg. Multiply 10 by 1,000.
How do I convert kilogram back to metric ton? +
Use metric ton = kilogram ÷ 1,000. The converter above handles both directions, or see our dedicated kg to tonnes page.
How accurate is this metric ton to kilogram conversion? +
The factor used is 1,000, carried at full double precision. Where a unit has an exact legal definition the factor is exact rather than approximate. Rounding is applied only to the displayed result, so the answer is never a calculation done on an already-rounded number.
Is there a quick way to estimate t to kg in my head? +
Multiply by 1,000. That matches the true factor of 1,000 exactly, so no adjustment is needed for a mental estimate.
