Kilograms to Tonnes Converter
1 kilogram = 0.001 tonnes
Distinct from the US short ton (2,000 lb) and the imperial long ton (2,240 lb).
1 kilogram equals 0.001 tonnes
How to convert kilograms to tonnes
These units measure mass. Pounds and ounces mean avoirdupois unless the unit explicitly says troy; a fluid ounce measures volume and requires a density to relate it to mass.
t = kg ÷ 1000One tonne corresponds to 1000 kilograms, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.
0.01 t = 10 ÷ 1000Distinct from the US short ton (2,000 lb) and the imperial long ton (2,240 lb).

The metric ton: exactly 1,000 kilograms.
Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
