Kilograms to Tonnes (kg to t) Converter
1 kilogram equals 0.001 tonnes — multiply kilograms by 0.001, or divide by 1000, to convert to metric tonnes. A metric tonne (t) is defined as exactly 1000 kilograms, so the conversion is clean and exact.
The formula
To convert kilograms to tonnes, multiply by 0.001:
tonnes = kilograms × 0.001
For example, 2500 kg × 0.001 = 2.5 t. To reverse, multiply tonnes by 1000.
