Does the size of the parcel determine the cost?

When it comes to the transportation of goods, one ultimately pays for space. Therefore courier shipments are charged either on volumetric weight or actual weight, both calculated in kilograms.

Actual weight of course is determined by simply weighing the parcel, while volumetric weight involves a little more work: measure the parcel in centimetres, and then multiply the three dimensions(width x height x length), and then divide by the conversion factor applicable to a particular service.

For example:

Size of parcel

  • Actual weight: 17 kg's
  • Volumetric weight: 60 cm x 70 cm x 43 cm = 180 600

(Divided by the Volume Conversion Factor) 4 000 = 45.15 kg's (round up to the nearest kg)

Volumetric weight = 46 kg's

The actual mass is 17 kg's while the volumetric weight is 46 kg's, therefore the chargeable mass is 46 kg's.

PLEASE NOTE: The conversion factor differentiation is as follows:

Volumetric Conversion Factor for road-freight: 4 000 Volumetric Conversion Factor for air-freight: 5 000
