An equivalent unit is a measure of containerized cargo capacity equal to one standard 20 ft (6.10 m) (length) × 8 ft (2.44 m) (width) container. As this is an approximate measure, the height of the box is not considered. For instance, the 9 ft 6 in (2.90 m) high cube and the 4 ft 3 in (1.30 m) half height 20 ft (6.10 m) containers are also called one TEU.
