- One carton
- 0.0300 m³
- Cubic feet
- 10.59 ft³
Measure the outer carton. Sea freight and containers use CBM. Cubic feet is the same volume in feet.
How to use it
- Enter length, width, and height of one carton in centimetres.
- Enter the number of cartons.
- Use the total CBM on the container and freight tools.
How the figure is worked out
CBM = (length × width × height × cartons) ÷ 1,000,000. Dimensions are in centimetres.
Questions
Should I include packaging in the measurement?
Yes. Measure the outer carton, the size the forwarder will stack.
How many centimetres make one CBM?
One cubic metre is 100 × 100 × 100 centimetres, so the calculator divides length × width × height × cartons by 1,000,000.
Can I use this for a container?
Yes. Take the total CBM into the container load calculator to see how many 20ft or 40ft boxes the cartons need.
