How to calculate the volume and chargeable weight of a consignment
Measure each package in the consignment (in metres) and multiply together the length, width and depth.
For example:
Actual weight = 10 kilos
0.4m x 0.1m x 1.2 = 0.048m3 (cubic metres)
UK domestic deliveries by road
The calculation is based upon 5 cubic metres = 100 kilos (1 tonne) chargeable.
To calculate the chargeable weight multiply the actual volume of each package by 200.
Thus, in the above example 0.048m3 x 200 = 9.6 kilos.
As the actual weight is 10 kilos the consignment is charged as 10 kilos as this is higher than the volume based chargeable weight of 9.6 kilos.
Air Freight
This traffic is moved by 'air' and the calculation is based upon 6m3 = 1000 kilos chargeable.
To calculate the chargeable weight multiply the actual volume of each package by 166.6.
Thus, in the above example 0.048m3 x 166.6 = 7.99 kilos.
As the actual weight is 10 kilos the consignment is charged as 10 kilos as this is higher than the volume based chargeable weight of 7.99 kilos.
International Road and Ferry Freight
This traffic is moved by 'road' and 'sea ferry' and the calculation is based upon 3m3 = 1000 kilos chargeable.
To calculate the chargeable weight multiply the actual volume of each package by 333.3.
Thus, in the above example 0.048m3 x 333.3 = 15.99 kilos.
The actual weight is only 10 kilos but in this case the volume based 'chargeable' weight is 16 kilos.
Deep Sea freight
This traffic is moved by 'sea freight' and the calculation is based upon 1m3 = 1000 kilos chargeable.
To calculate the chargeable weight multiply the actual volume of each package by 1000. Thus, in the above example 0.048m3 x 1000 = 48 kilos.
The actual weight is only 10 kilos but in this case the volume based 'chargeable' weight is 48 kilos.
However, the minimum charge is always 1m3
