CBM calculator
Convert the dimensions of identical rectangular packages into cubic metres.
CBM means cubic metres. Multiply the outside length, width and height in metres, then multiply by the number of packages.
Calculate your cargo volume
Calculated on your device. These fields are not uploaded or saved by this calculator.
Formula and worked example
Total volume (m³) = length (m) × width (m) × height (m) × quantity.
Ten boxes measuring 40 × 30 × 20 cm have a total outside volume of 0.24 m³: 0.4 × 0.3 × 0.2 × 10.
Use the result in a loading plan
- Use the outside package dimensions and select their unit.
- Enter the number of identical packages to calculate their total volume.
- For different package sizes, calculate each group separately or import the complete list into the planner.
Questions about this calculation
Does CBM tell me how many containers I need?
Volume alone does not establish geometric fit. Dimensions, loading access, orientation, mass and handling restrictions can leave space unusable.
Can I enter inches?
Yes. The calculator converts inches to metres before multiplying; one inch is exactly 0.0254 metres.
Does it calculate freight charges?
No. The result is physical outside volume. Carrier charging rules, minimum charges and volumetric-weight factors are separate.
