Q:- How to calculate Volumetric Weight...
A:- 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 is sent to compare this with it's actual weight. The greater weight of the two is used to calculate the price that is charged.

Volumetric Calculation

D x W x H (cms) divided by 5000 = Weight (kgs)

International Example:

40 X 20 X 30 = 24000, divided by 5000 = 4.8 kgs

Click here for the International Calculator - Volumetric Weights are calculated using the formula:-
Depth x Width x Height (centimetres) divided by 5000 = Volumetric Weight (kilograms)

Click here for the Domestic Calculator - Volumetric Weights are calculated using the formula:-
Depth x Width x Height (centimetres) divided by 4000 = Volumetric Weight (kilograms)
