How to use this tool

A decision, not just an output

Convert carton dimensions and quantity into cubic meters, cubic feet, and a reference container utilization. Read the output alongside its interpretation, assumptions, limitations, and source. Marketplace rates and external requirements should always be confirmed at the linked official source.

Formula & example

Transparent method

CBM = carton length in meters × width in meters × height in meters × quantity.

Example: Two 100 × 100 × 100 cm cartons occupy 2 CBM and about 70.63 cubic feet.

Assumptions

  • • Cartons are rectangular and use outside dimensions.
  • • Reference capacity is planning space, not guaranteed loadable volume.

Limitations

  • • Weight limits, pallets, unusable space, and carrier rules can reduce actual capacity.
