How to convert kilograms to tonnes
Multiply the value in kg by 0.001: the result is in t.
Where these two units are used
The kilogram is the only SI base unit whose name still carries a prefix, and since 2019 it no longer depends on a platinum cylinder but on the Planck constant. The tonne is a thousand kilograms and serves freight, steel and carbon dioxide emissions; it has nothing to do with the American short ton of 907 kilograms nor the British long ton of 1016. The threshold is crossed at loading: a lorry is weighed in kilograms on the weighbridge and declared in tonnes on the consignment note, three zeroes apart from measurement to paperwork.
