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.
