Tonnes and kilograms, side by side
One tonne is 1,000 kg. In the other direction, one kilogram is 0.001 t.
Both are metric units, so the factor is a power of ten and the conversion is exact: it only moves the decimal point.
The tonne, or metric ton, is 1,000 kilograms. It is not the American short ton (2,000 pounds, about 907 kg) or the British long ton (2,240 pounds, about 1,016 kg), which is why trade and shipping say which ton they mean.
The kilogram is the base unit of mass in the International System. Since 2019 it has been defined through the Planck constant, replacing the platinum-iridium cylinder kept near Paris that had been the standard since 1889. A liter of water has a mass of about one kilogram.
