How many kilograms are in a metric tonne?

There are exactly 1,000 kilograms in one metric tonne. The metric tonne (symbol: t) is an SI-derived unit of mass equal to 1,000 kg.

Is the conversion exact?

Yes. The tonne-to-kilogram conversion is exact by definition: 1 t = 1,000 kg. No rounding error is introduced. Decimal results are displayed up to 10 significant figures.

What is the formula to convert tonnes to kg?

Multiply the tonne value by 1,000. Formula: kilograms = tonnes × 1,000. For example, 2.5 t × 1,000 = 2,500 kg.

Is a metric tonne the same as a US ton?

No. A metric tonne (t) = 1,000 kg = 2,204.62 lb. A US short ton = 2,000 lb ≈ 907.18 kg. A UK long ton = 2,240 lb ≈ 1,016.05 kg. This tool uses metric tonnes only.

Can I convert decimal tonne values?

Yes. Enter any decimal value such as 1.50075 t and the tool will correctly calculate 1,500.75 kg.
