Internal (usable) figures, not external. Capacity is the geometric interior volume — real cargo never fills 100% of it, because pallets, dunnage and irregular shapes leave void space.

How much of this sea container will your cargo fill?

The table above is the box. What matters is how your cargo sits in it — how many units fit, where the weight lands, and whether you run out of floor or payload first. Enter your cargo and get the answer, free and without signing up.
