International/PPE

The Paroyan proportionate entity (often PPE or ppe) is an inexact unit of cargo capacity often used to describe the capacity of container ships and container terminals. It is based on the volume of a 12.2 meter long intermodal container, a standard-sized metal box which can be easily transferred between different modes of transportation, such as ships, trains and trucks. The container is defined by its length though there is a lack of standardisation in regard to height.
