Gross weight including contents and packaging for one carton.
kg
Carriers divide the carton volume in cm3 by this number to get volumetric weight in kg. Sea freight often uses 1 CBM = 1000 kg (W/M ratio) instead; air couriers typically use 6000.
Practical usable volumes are lower than the nominal internal volume to allow for irregular stacking and dunnage.

Total shipment: 7.200 CBM, chargeable weight 1500.0 kg.

  • Your 100 cartons occupy 7.200 m3 in total.
  • That fills 28.8% of a 20 ft standard container (usable volume).
  • Actual weight (1500.0 kg) exceeds volumetric weight (1200.0 kg), so freight will be charged on actual weight.
