How to calculate CBM

CBM means cubic metres: the volume occupied by your shipment. Use the packed outer dimensions, including any packaging that extends beyond the carton.

Length × width × height × cartonsDimensions converted to metres first

Example: 60 × 40 × 40 cm × 12 cartons = 1.152 m³. For mixed cartons, calculate each type and add the volumes.

Before you quote freight

Is CBM the same as chargeable weight?

No. CBM measures volume. A carrier may charge by gross weight, volumetric weight or minimum shipment rules. Confirm their divisor and rounding rules separately.

Does this predict container capacity?

It adds geometric volume only. It does not account for stacking, load restraints, carton rotation, access space or safe load limits.

How are values rounded?

Displayed values use up to six decimal places. A non-zero result smaller than 0.000001 is shown in scientific notation. Calculations use the unrounded values.
