a twenty-foot equivalent unit (often TEU or teu ) is an improper cargo capacity unit often used to describe the capacity of container ships and container terminals. It is based on a 20-foot (6.1 m) intermodal container volume, a standard-sized metal box that can be easily transferred between different modes of transport, such as ships, trains and trucks.
The container is defined by its length although there is a lack of standardization in terms of altitude, ranging between 4 feet 3 inches (1.30 m) and 9 feet 6 inches (2.90 m), with the most common altitude being 8 feet 6 inches (2.59 m ). Also, it is common to designate 45-foot containers (13.7 m) as 2 TEUs, rather than 2.25 TEUs.

Units equivalent to Forty-foot
The standard intermodal container is set by twenty feet long and 8 feet wide (2.44 m). In addition there is a standard container of the same width but a length of twice that of forty feet called a 40-foot container, which equals one forty feet equivalent unit (often FEU or feu ) in cargo transport (considered two TEUs, see below).
To allow this type of buildup, the forty-foot intermodal container has a maximum length of 40 feet (12,192 m), while the standard twenty-foot standard intermodal container is slightly shorter with a precise length of 19 feet 10.5 inches (6,058 m). I). The rotating motion on the ship is placed at a considerable distance so that two standard twenty-foot containers have a three-inch gap that allows a forty-foot container to be placed on it.
The four-meter container has gained wider acceptance, as it can be towed with a semi-trailer truck. The length of the combination is within the limits of national road regulations in many countries, which do not require special permission. Because some road rules allow longer trucks, there are also standard forty-foot container variations - in Europe and most other places containing 45 feet (13.72 m) can be pulled as a trailer. Containers 48 feet (14.63 m) long or 53 feet (16.15 m) are restricted to road transport in the United States. Although more than 40 feet, this variant is placed in the same class with a unit equivalent to forty feet.
Container ships only take containers 40 feet and 20 feet below the deck, plus containers 45 feet above the deck. Ninety percent of containers carried by container ships are 40 feet. Since container ships carry 90% of the world's freight, at least 81% of overseas shipments in the world move through 40-foot containers.

Equality
Because TEU is an incorrect unit, it can not be properly converted into another unit. The corresponding unit forty foot equivalent unit , however, is defined as two TEUs. The most common dimensions for 20-foot (6.1 m) containers are 20 feet (6.1 m) in length, 8 feet (2.44 m) wide, and 8 feet 6 inches (2.59 m) high, for volume of 1,360 cubic feet (39 m 3 ). However, the height of the 9-foot-6-inch-high box (2.90 m) high cube and 4-foot-3-inch (1.30 m) half height is also calculated as 1 TEU. This gives a range of 680 to 1,520 cubic feet (19 to 43 m 3 ) for one TEU.
While TEU itself is not a measure of mass, some conclusions can be drawn about the maximum mass that can represent TEU. The maximum gross mass for 20-foot dry cargo containers (6.1 m) is 24,000 kilograms (53,000 pounds). Reducing the tare mass from the container itself, the maximum amount of cargo per TEU is reduced to approximately 21,600 kilograms (47,600 pounds).
Similarly, the maximum gross mass for a 40-foot (12.2 m) dry cargo container (including 9-foot-6-inch-high (2.90 m) cube container is 30.480 kilograms (67,200 lb). , this provides a cargo capacity of 26,500 kilograms (58,400 pounds).
A twenty-foot container, "heavy tested" is available for heavy items such as heavy machinery. This container allows a maximum weight of 67,200 pounds (30,500 kg), an empty weight of 5,290 pounds (2,400 kg), and a net load of 61,910 pounds (28,080 kg).
