For air cargo, carriers take the volumetric weight of the goods, rather than the gross weight.
To work this out you use the following calculation…
length x width x height (cm) / 6000 = volumetric weight kg
120cm x 100cm x 80cm = 960,000
/ 6000 = 160 kg (volumetric)
Some airlines, especially couriers, divide by 5000, so please check with the Ligentia Customer team first
