In air freight, carriers charge based on whichever is higher: the actual gross weight of your shipment, or its volumetric weight — a calculated figure that represents how much space the cargo occupies in the aircraft's hold. This prevents light but bulky cargo from being transported at the same rate as dense goods.
The standard formula is: Volumetric Weight (kg) = L × W × H (cm) ÷ 6,000. Most IATA member airlines use a divisor of 6,000 (so 1 m³ = 166.67 kg chargeable weight). Express carriers — FedEx, UPS, DHL — typically use 5,000, making volumetric weight relatively heavier and more likely to apply.
Volumetric Weight (kg) = (L × W × H in cm) ÷ Factor
— Factor = 6,000 (IATA standard) or 5,000 (express)
