Calculate the volumetric weight of your shipment. Sometimes, large items with a light overall weight can be charged according to the space they take up on aircraft In these cases, Volumetric Weight, or dimensional (Dim) weight, is used to calculate the shipment cost.
It is recommended that you calculate the Volumetric Weight for every shipment that you send, then compare this to its actual weight. The greater weight of the two is used to work out the price that we charge you.
Volumetric Weights are calculated using the formula below
Volumetric Weight = (length x width x height ) ÷ dimensional factor*
