Actual weight is the weight in KGs of the package. Includes the weight of packaging and label.
Volumetric weight is calculated using the formula below:
Width x Length x Height in centimetres / 6000 (Varies depending on courier) = Volumetric Weight in KGs.
Therefore if you send a 1 KG parcel with of size 60*30*20 cm with DHL, its volumetric weight will be: 60*30*20/5000 = 7.2 KG.
Compare the package's actual weight to its volumetric weight. The larger of the two weights is the billable weight and should be used to calculate the rate.
