The Twenty-foot Equivalent Unit (often TEU or teu) is an inexact unit of cargo capacity often used to describe the capacity of container ships and container terminals.[1] It is based on the volume of a 20-foot long shipping container, a standard-sized metal box which can be easily transferred between different modes of transportation, such as ships, trains and trucks.[1] A related unit, the forty-foot equivalent unit (often FEU or feu) is defined as two TEU.
One TEU represents the cargo capacity of a standard shipping container 20 feet long and 8 feet wide.[1] One source of ambiguity is the lack of standardization in container heights. The height of a TEU can range from a low of 4.25 feet (1.30 m) to the most common 8.5 feet (2.6 m) to 9.5 feet (2.9 m).[2] Also, it is common to designate 45-foot containers as 2 TEU, rather than 2.25 TEU.[3]
