Metric tons (tonnes) to Kilograms (t to kg)
Convert metric tons (tonnes) to kilograms: 1 t = 1000 kg. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 t = 1000 kg
kilograms = metric tons (tonnes) × 1000 — reverse: metric tons (tonnes) = kilograms × 0.001
The factor is derived from the SI definitions of both units (base unit: kg) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.
Worked examples
- 5 t = 5000 kg
- 12.5 t = 12500 kg
- 100 t = 100000 kg

FAQ
How many kilograms are in one tonne?
1 t = 1000 kg. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.
What is the formula to convert metric tons (tonnes) to kilograms?
Multiply the value in metric tons (tonnes) by 1000: kilograms = metric tons (tonnes) × 1000. For example, 5 t = 5000 kg.
How do I convert kilograms back to metric tons (tonnes)?
Multiply by the inverse factor 0.001 (metric tons (tonnes) = kilograms × 0.001), or use the kilograms-to-metric tons (tonnes) page.
