The dimensions of shipping containers are often provided in both imperial and metric sizes. This is due to the fact that in the USA the imperial system is used, but in Europe the metric system is used to refer to the same container. For instance, in the imperial system, the 6-metre container is the 20-foot container, and the longer 12-metre container is the 40-foot container. The lower DC container has a height of 2.59 m and the higher HC container has a height of 2.9 m.
