Explained

What is volumetric weight?

Aircraft and delivery vehicles run out of space before they run out of weight capacity. So carriers charge light, bulky parcels on the space they occupy - their volumetric (or dimensional) weight.

Measure the longest point of each side in centimetres, multiply length × width × height and divide by the carrier's divisor. Your chargeable weight is the higher of that figure and the actual weight.

Worked example

A 60 × 40 × 40 cm carton weighing 8 kg, sent by express courier:

60 × 40 × 40 = 96,000 cm³

96,000 ÷ 5,000 = 19.2 kg volumetric

max(8, 19.2) = 19.5 kg chargeable

Courier weights are rounded up to the next 0.5 kg. Repacking into a 50 × 40 × 30 cm box would cut the chargeable weight to 12 kg.
