Volumetric weight per piece = L × W × H ÷ divisor. Chargeable weight = max(gross, volumetric), summed over all pieces. Figures are for planning — your carrier's measurement and rounding always prevail.
Airlines sell space, not just weight. A light but bulky box takes up room that could carry heavier cargo, so carriers compare the actual (gross) weight with the volumetric weight — and bill whichever is higher.
10 cartons, each 60 × 40 × 40 cm, 8 kg gross. Volumetric per carton = 60 × 40 × 40 ÷ 6000 = 16 kg — higher than the 8 kg gross, so you are billed 16 × 10 = 160 kg, not 80 kg. Try it: hit "Load example" above.
