The cost of transporting a shipment can be affected by the amount of space that it occupies on an aircraft, rather than the actual weight.

This is the volumetric (or dimensional) weight.
The volumetric weight of a shipment is a calculation that reflects the density of a package.
A less dense item generally occupies more volume of space, in comparison to its actual weight.

The volumetric or dimensional weight is calculated and compared with the actual weight of the shipment to
ascertain which is greater; the higher weight is used to calculate t he shipment cost.

Calculating Volumetric Weight

Volumetric weight is calculated by multiplying the length x height x width of a package and dividing the result by a
volumetric factor.
That factor varies with the unit of measure. Since we use kilograms to
calculate shipping charges, we use the
following formulas to calculate volumetric weight:
