Volumetric weight is usually calculated for packages on cargo and shipment in order to reflect the density of the package. This is because a less dense item can occupy more space compared to its actual weight.
Volumetric weight is calculated by multiplying the length x height x width of a package and dividing the answer by a volumetric factor. Volumetric Weight is therefore obtained by the following formula:
Volumetric Weight = (Length x Height x Width)/5000 if the dimensions are in centimetres
Volumetric Weight = (Length x Height x Width)/305 if the dimensions are in inches.
