Air Freight Volumetric Dimensions 6000 cubic centimeters per kilograms. 366 cubic inches per kilograms. 166 cubic inches per pound. Example: Volumetric calculation Example: Volumetric calculation 1 pallet: 120 x 100 x 90 cm Actual Volume – 1.2 x 1.0 x 0.9 = 1.26 cubic meters Calculating Volumetric Weight 1.26 Cbm Divide / by 0.006 = 210 – This will become the volumetric weight of the shipment in Kilograms. The actual weight of the pallet may be 150 kgs from which the Airfreight will be charged against the volumetric weight 210 kgs. If the pallets actual weight is 260 Kgs it would be charged against the actual weight of the shipment.
