What is CBM?

CBM (Cubic Meter) is the standard unit used in logistics to measure the volume of cargo. It helps freight companies calculate how much space your shipment will occupy inside a container or truck.

CBM formula

CBM = (Length × Width × Height) × Quantity

If the dimensions are entered in centimeters, they are converted to meters automatically:
CBM = (L/100 × W/100 × H/100) × Quantity

CBM example

Example:
A box measuring 50 × 40 × 30 cm and a total of 10 boxes:
CBM = (0.5 × 0.4 × 0.3) × 10
CBM = 0.6 m³
This means the shipment will occupy 0.6 cubic meters of container space.

When should you use this CBM calculator?

  • When preparing shipments for sea freight or air freight.
  • When comparing container sizes (20ft, 40ft, 40HQ).
  • When calculating how many boxes fit on a pallet or in a container.
  • When estimating shipping cost based on volume.
  • When you need accurate m³ for international export documents.

How this CBM calculator helps your business

  • Reduce shipping cost by optimizing carton sizes.
  • Avoid paying for unnecessary container space.
  • Improve packing and pallet planning.
  • Get accurate freight quotations faster.
  • Prepare export documents with correct m³ values.

CBM Calculator – Frequently Asked Questions

  • What is CBM used for?

    CBM is used by shipping companies to determine the space your cargo occupies and to calculate freight cost.

  • Can I use this calculator for multiple boxes?

    Yes. Set the quantity field to the number of identical boxes. The tool multiplies the CBM of one box by the quantity.

  • What units should I enter?

    You can enter dimensions in centimeters or meters. The calculator converts them and returns the result in cubic meters (m³).

  • Is CBM important for air freight?

    Yes. Air freight often uses volumetric weight, which is based on the CBM of your shipment.
