Quick Summary: Volumetric Weight Formula
The air freight volumetric weight formula is: Volumetric Weight (kg) = (Length x Width x Height in cm) / 5000. Airlines compare actual scale weight against volumetric weight and bill the higher figure as the "chargeable weight".
Practical Volumetric Weight Example
Example Box Dimensions:
Box dimensions: 50 cm (L) x 40 cm (W) x 40 cm (H)
Volume = 50 x 40 x 40 = 80,000 cm³
Volumetric Weight = 80,000 / 5000 = 16.0 kg
If actual scale weight is 10 kg, the chargeable weight is 16 kg. If actual scale weight is 20 kg, the chargeable weight is 20 kg.
