Question: 1 teu is how many tons?
Answer: This gives a volume range of 680 to 1,520 cubic feet (19 to 43 m3) for one TEU. While the TEU is not itself a measure of mass, some conclusions can be drawn about the maximum mass that a TEU can represent. The maximum gross mass for a 20-foot (6.1 m) dry cargo container is 24,000 kilograms (53,000 lb).
