1 tonne is 1.1 ton. One tonne is exactly 1.10231131092 US tons.
One tonne is 1.1023113 US tons. To convert tonnes to US tons, multiply by 1.1023113; to go the other way, divide by 1.1023113 or multiply by 0.90718474. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 44. One thousand kilograms, also called the metric ton — 2,204.6 pounds.

How do you convert tonnes to US tons? The converter and the working
- 1.Take the measurement in tonnes.
- 2.Multiply by 1.1023113 — that is how many US tons fit in one tonne.
- 3.To go back the other way, divide by 1.1023113, or multiply by 0.90718474.
Worked example: 25 tonnes to US tons
- Formula
- t × 1.1023113 = ton
- Arithmetic
- 25 × 1.1023113 = 27.56 ton
- Answer
- 25 t = 27.56 ton
The factor is rounded for display; the figure above is computed from the full value.

Three different tons, ten per cent apart
The US short ton is 2,000 pounds, or 907.18474 kg. The metric tonne is exactly 1,000 kg. The British long ton is 2,240 pounds, or 1,016.0469088 kg. Freight quotes, emissions figures and scrap prices all use "ton" without saying which, and the spread between the extremes is twelve per cent.
