Cargo volume calculator (CBM)
For rectangular packages, CBM is external length × width × height in metres × package count. Add the volume of each package size. Include pallets and packaging; provide actual gross weight separately.

Enter the packed dimensions
Include external packaging and pallets. Units are per row; measurements have millimetre precision. Omit thousands separators; write 1500, for example.
Total geometric volume (CBM)
Complete all dimensions and counts to calculate.
Formula and worked example
CBM = L(m) × W(m) × H(m) × quantity
Example: ten packages measuring 120 × 80 × 100 cm have a total geometric volume of 9.6 m³. This example describes dimensions, not a standard pallet specification.
Interpreting the result and packing limits
Geometric volume is one input to a shipment review. Door openings, package shape, stacking, weight distribution, handling equipment and securing must also be checked. For refrigerated cargo, state the product and required temperature separately. The result is not a container loading plan, a booking or a freight price.
Calculations run in your browser. Dimensions are copied to temporary tab storage only when you choose to use them in an enquiry; they expire after 30 minutes. No contact details are collected by this calculator.
Frequently asked questions
Can I mix centimetres and metres?
Yes. Choose the unit for each row. Enter external dimensions including packaging and a whole-number package count.
Does CBM confirm which container I need?
No. A small total volume can still include a package that does not pass through a door or cannot be stacked. Send dimensions, gross weight and handling constraints for review.
Does this tool calculate chargeable weight or freight cost?
No. It calculates geometric volume. The applicable rating basis and service scope must be confirmed in the freight proposal.
