Tonnes to kilograms
1 tonne = 1,000 kilograms
Type a value in tonnes (t) to get kilograms (kg) straight away. A tonne is larger than a kilogram, so the number goes up. Both units belong to weight, measured here against the kilogram.
1 t = 1,000 kg
Formula
kg = t × 1,000
One tonne is 1,000 kilograms, so multiply the tonne value by that factor. Here t is the value in tonnes and kg is the result in kilograms.
Worked example: 2 tonnes × 1,000 = 2,000 kilograms.
