How do you convert long tons to US tons? The converter and the working
- 1.Take the measurement in long tons.
- 2.Multiply by 1.12 — that is how many US tons fit in one long ton.
- 3.To go back the other way, divide by 1.12, or multiply by 0.89285714.
Worked example: 25 long tons to US tons
- Formula
- LT × 1.12 = ton
- Arithmetic
- 25 × 1.12 = 28 ton
- Answer
- 25 LT = 28 ton
The factor is exact, so this figure is exact too — only the display is rounded.

Three tons, and a shipping document may mean any of them
The US short ton is 2,000 lb, the British long ton is 2,240 lb, and the metric tonne is 1,000 kg — 2,204.62 lb, sitting between the two. A long ton is 12% heavier than a short one, which on a bulk cargo is the difference between a full hold and a short delivery. Freight rates written simply in "tons" are worth reading twice.
