Container basics

forty-foot equivalent unit (FEU)

A forty-foot equivalent unit is a unit of cargo capacity based on a 40-foot-long intermodal container. One FEU equals two TEU. Shipping lines, ports and freight forwarders use it, often next to TEU, to count containers of different lengths in one clear number.

Why it matters

FEU appears in freight quotes, port data and some lessor reports. It counts each 40-foot box as one unit. A port that handles 1,000 FEU has moved 1,000 40-foot containers, or 2,000 TEU. For portable storage operators, the main use is reading wholesale offers and trade reports that mix 20-foot and 40-foot units. If a supplier quotes a volume, ask whether the number counts boxes, TEU or FEU, and ask for the count of boxes by size. A common mistake is to compare a TEU number and an FEU number as if they used the same base. Convert first. Also remember that FEU counts length, not weight or load.
