We can calculate the CBM in kgs by multiplying the total freight volume with the dimensional factor, such that,
Volumetric Weight = CBM x DIM Factor
The dimensional factor varies for sea, air, and road transport. A 60 cm x 10 cm x 10 cm (6000 CBM) box used in air transport (DIM - 1:6000) is 1 kg (volumetric weight). Similarly, a 10 cm x 10 cm x 10 cm carton (1000 CBM) in ocean freight is 1 kg (volumetric weight).
