Chargeable Weight was created as a conversion factor for air freight in order to bridge the difference between volume and weight. After all, 1,000 KGs of feathers requires a larger volume than 1,000 KGs of lead. In order to be able to charge this difference equally, a conversion factor was called into life.
With air freight, 1 cubic metre (CBM) equals 167 KGs. Sea freight LCL, 1 CBM equals 1,000 KGs, while with road transport 1 CBM equals 333 KGss (measuring 3 times). The highest weight (volume or actual) is charged.
