CBM calculator: cubic meters of a shipment

Independent site, not a government agency or a customs broker. General information, not legal advice or customs advice.

Enter the size of one carton and how many you have: the volume of the shipment and what share of a container it fills.

A cubic meter, or CBM, is a measure of a shipment’s volume. To find it, multiply length by width by height in meters for one carton, then multiply by the number of cartons. In centimeters, divide the product by one million. So a carton of 60 by 40 by 40 cm is 0.096 CBM, and 100 of them are 9.6 CBM. We print no container capacity, because we could not verify one at a source we may reuse on November 2, 2026: your carrier’s sheet gives it. Use the figure for planning, then ask your forwarder for a load plan. The second tool checks both volume and weight against the figures you enter, and tells you which of the two runs out first with those numbers.

The formula, by hand

In centimeters: length × width × height ÷ 1,000,000 × cartons. In inches: length × width × height ÷ 1,728 gives cubic feet, and dividing by 35.31 gives CBM. Measure the outside of the carton after packing. One centimeter more on each side of a thousand 60 by 40 by 40 cm cartons adds about 2.9 cubic meters.

Volume fits, but does the load?

A volume says nothing about how cartons stack or go through the door. The pallet calculator handles a palletized load, and the container page lists the figures to get from your carrier.

From volume to weight

If your carrier bills by a volume weight, use the chargeable weight calculator.

Questions importers ask

How many CBM fit in a 40-foot container?

We state no figure, because we could not verify one at a source we may reuse. Your carrier’s sheet gives the capacity of the empty box, and you can enter it in the second tool, with your own volume and weight. How much of it your cartons can use depends on their size and your stacking limits, so ask your forwarder for a load plan, which will give you a figure for your own goods.

What is the difference between CBM and cubic feet?

They measure the same thing in different units. One cubic meter equals about 35.31 cubic feet, so 10 cubic meters are about 353 cubic feet. The calculator gives both, so you can compare quotes in either unit without converting by hand. Check which unit each quote uses, because the same number means very different volumes in the two units.

Does this calculator tell me the freight price?

No. We publish no freight rates, as we read no official source for them, and they are private prices. The tool gives you the volume, which you can put to a forwarder for a quote. Ask the quote to state its unit and any minimum. Then enter the amount under your costs in the landed cost calculator to see it next to your duties and fees.
