How CBM calculations work
Cubic Metres (CBM) is the standard volume unit for shipping. For any package, CBM is computed as:
Volume = (Length × Width × Height in cm × Quantity) ÷ 1,000,000
Airlines and ocean freight operators apply a volumetric ratio to bill bulky but lightweight cargo fairly. Air freight usually bills at a 1:6000 ratio (1 CBM = 167 kg), whereas Ocean LCL shipping uses a 1:1000 ratio (1 CBM = 1000 kg).
