Free CBM calculator

Volume, chargeable weight and container fill for sea, air, courier and road — and which of volume or weight is actually driving the cost, because that is the fact that changes what you do next.

• Sea compares cubic metres with tonnes; air compares actual kilos with volumetric
• Container volumes are usable, not nominal: 28, 58 and 68 CBM
• A 40-foot container carries less weight than a 20-foot one
• Air is charged at 1 m³ = 167 kg, couriers at 200 kg, road groupage at 333 kg
