Questions About CBM and Chargeable Weight
What does a CBM calculator do?
A CBM calculator converts package dimensions into cubic meters so shippers can estimate shipment volume and compare air or sea freight requirements.
Why is chargeable weight sometimes higher than actual weight?
Chargeable weight can be higher than actual weight when the shipment is bulky and volumetric weight exceeds gross weight, especially for air freight.
When should I use the CBM calculator?
Use the CBM calculator before booking freight so you can estimate volume, chargeable weight, and the likely impact of packaging on freight cost.
