Amazon FBA Volumetric Weight Calculator
Determine whether your consignment is charged on physical scale weight or dimensional weight across Air Express (1:5000) and Dedicated Air Freight (1:6000).
• Air Freight Volumetric: (L cm × W cm × H cm) ÷ 6,000 (1 CBM = 167 kg)
• Express Courier: (L cm × W cm × H cm) ÷ 5,000 (1 CBM = 200 kg)
• Chargeable Weight = Max(Gross Physical Weight, Volumetric Weight)

Why Dimensional Weight Matters for Amazon Sellers
Airlines and cargo vessels have physical volume constraints as well as weight limits. A carton filled with light plush toys takes up substantial aircraft cargo hold space while weighing very little, whereas a carton of stainless steel kitchenware takes up little space but is very heavy.
To balance this discrepancy, IATA and international parcel carriers enforce the Chargeable Weight rule: carriers bill whichever number is larger between actual weight and dimensional weight. By consolidating with FBAbridge, your lightweight products can be cross-balanced against dense products to achieve optimal billable rates.
