Frequently Asked Questions
How is CBM calculated?
In centimeters: CBM = (Length × Width × Height) / 1,000,000 × Quantity. In meters: CBM = Length × Width × Height × Quantity.
What is the difference between air freight divisors 6,000 and 5,000?
IATA standard air cargo uses divisor 6,000 (1 CBM = 167 kg), while express couriers such as DHL, FedEx, and UPS typically use divisor 5,000 (1 CBM = 200 kg) to calculate volumetric weight.
