Calculate cubic meters (CBM) and cubic feet from carton dimensions in centimeters or inches. Use it for LCL shipments, ocean freight planning, air cargo estimates, warehousing and pallet/container planning.
Enter dimensions and quantity
CBM means cubic meter. In freight shipping, CBM measures the volume of cargo. It helps forwarders, carriers, warehouse teams and importers understand how much space a shipment needs in a container, truck, aircraft or warehouse.
CBM is especially common in ocean freight and LCL shipping because cargo is often planned and priced by volume. Even when weight matters, volume still affects loading, pallet planning and storage decisions.
For centimeters:
For inches, convert dimensions to meters first, or use the calculator above.
Estimate shipment volume before requesting rates or booking space.
Compare cargo volume against available space in 20ft and 40ft containers.
Use volume as part of dimensional or chargeable weight checks.
Estimate how much storage space cartons or pallets may require.
Multiply length × width × height, then divide by 1,000,000. Multiply the result by the number of cartons or units.
One CBM is approximately 35.315 cubic feet.
Yes, but air freight normally uses chargeable weight, which compares actual weight against volumetric or dimensional weight. CBM still helps estimate cargo volume.
No. Final freight cost can depend on weight, route, carrier, handling, packaging, fuel, surcharges, customs, accessorials and contract rates.
