CBM Calculator
Calculate cubic meters (CBM) for cartons and shipping cargo.
What is CBM?
CBM means cubic meter and is a standard volume measurement used in freight and logistics.
CBM formula
CBM = Length × Width × Height × Quantity
Example
A carton measuring 60 cm × 40 cm × 30 cm is 0.072 m³. Ten cartons occupy 0.72 CBM.
CBM for cartons and freight
CBM means cubic meters and represents physical cargo volume. Convert carton dimensions to meters, multiply length by width by height, then multiply by the number of cartons. If different carton sizes are used, calculate each group separately and add the volumes.
CBM is not chargeable weight
Sea freight, air freight and couriers can price shipments using different rules. CBM describes volume, while chargeable weight may compare actual weight with a dimensional or volumetric weight formula. Always check the carrier or forwarder formula before estimating a final freight charge.
Frequently Asked Questions
How do I convert cm to CBM?
Multiply length × width × height in cm, then divide by 1,000,000 and multiply by quantity.
Is CBM the same as weight?
No. CBM is volume.
How many cubic centimeters are in one CBM?
One cubic meter equals 1,000,000 cubic centimeters.
Should pallet dimensions be included in CBM?
If the shipment is tendered on pallets and the carrier charges based on the palletized dimensions, use the actual outer dimensions of the loaded pallet.
