CBM Calculator: Calculate Shipment Volume
Use this free CBM calculator to calculate cubic meter shipment volume from dimensions and quantity, with cubic feet conversion and a clear formula.
CBM formula
Per-package CBM = length (m) × width (m) × height (m)
Total CBM = per-package CBM × quantity
Convert each dimension to metres before multiplying.
How to calculate CBM
Convert length, width, and height to metres, multiply them for one package, then multiply by the number of identical packages.
Worked example
A package measuring 100 × 50 × 40 cm is 0.2 CBM. Ten identical packages total 2 CBM.
CBM conversion calculator: cubic metres and cubic feet
This calculator uses 1 CBM = 35.3146667 ft³. It converts the total only after calculating the full-precision cubic metre volume.
Use CBM in shipment planning
CBM helps you describe shipment size when researching route options. Freight planning may also depend on weight, cargo type, timing, origin, destination, and current availability.
CBM is not dimensional or chargeable weight
CBM measures volume. Dimensional weight and chargeable weight apply separate carrier or mode-specific rules and are not calculated by this tool.
CBM calculator FAQs
How do I calculate CBM?
Convert every dimension to metres, multiply length by width by height, and multiply that per-package volume by the quantity.
How many cubic feet are in 1 CBM?
One cubic metre equals approximately 35.3147 cubic feet. This calculator shows both units for the total shipment.
Does CBM determine the shipping price?
No. CBM describes cargo volume, but route, weight, cargo type, timing, surcharges, and availability may also affect freight planning.
Is CBM the same as dimensional weight?
No. CBM is a volume measurement. Dimensional and chargeable weight use separate rules that vary by transport mode or provider.
