The CBM of a shipment is calculated by multiplying its length, width, and height:
CBM (m3) = L * W * H
For example, an item that is 2.5 m in length, 2.0 m in width, and 3.0 m in height would be 15 CBM. To account for items of varying sizes, determine the CBM of each and add them together. For irregular shapes, only consider the longest dimensions.
To calculate the CBM of cylindrical items, use the following formula:
π * Height * Radius² (m3) = CBM
