Cubic Meters Calculator - CBM Calculator (2024)

Whether you're shipping goods, managing storage space, planning a construction project, designing an interior layout, or ensuring import/exportcompliance, calculating cubic meter measurements can be an important part of your planning.

By accurately estimating the right amount of space, materials, or resources required, you can make maximum use of available space and plan foradditional capacity if needed.

Keep scrolling to learn how to calculate cubic meters manually (from feet, inches, meters and cm) and find out the dimensions and CBM measurements for themost common sizes of shipping container and trailer.

Let's continue this article with how to manually calculate cubic meter (CBM) measurements, assuming you don't want to use our calculatorat the top of the page.

How to calculate CBM

To calculate cubic meters (CBM), multiply the length, width, and height of an object or space (measured in meters) to obtain the total volume.CBM = length (m) × width (m) × height (m)

To ensure you calculate accurately, it's important that all of your measurements are in the same unit (in the above case, meters). We'll go throughthe formulae for calculating measurements in cm and feet below. But, for any conversions to and from meters, you can use ourlength converter.

Formulae for calculating cubic meters

• From meters: length (m) × width (m) × height (m)
• From cm: length (cm) × width (cm) × height (cm) ÷ 1000000
• From feet: length (ft) × width (ft) × height (ft) ÷ 35.3147

Let's go through an example calculation to demonstrate the process.

Example cubic meter calculation

We'll say you want to calculate the CBM volume of a box that measures 200cm x 200cm x 50cm. Your calculation would look something like this:

Calculations for shipping containers

If you're preparing to pack a shipping container, truck, or warehouse, you might find yourself needing to calculate cubic meter measurements in order toestimate space requirements.

Shipping containers come in a range of sizes, but the ones you'll most commonly find in the shipping industry are standard 20ft, 40ft, and 40ftHigh Cube containers. 1

With this in mind, let's go through the common dimensions, including cbm capacity, for 20ft and 40ft containers.

How many cubic meters does a 40 foot container measure?

A standard 40-foot container has an internal cubic capacity of around 67 cubic meters (2,366 cubic feet), Typically, you can fit around 54-58 cubic meters of goods inside, depending on the size and shape of items. 2

Below are some dimensions of a standard 40ft container. Note that dimensions may vary slightly between companies.

If you want the internal measurements in meters instead of feet, you're looking at a length of 12m, width of 2.3m and height of 2.4m.

It's important to keep in mind that although a 40ft container offers a total space of 67 cubic meters, it is unlikely that you will beable to achieve 100% capacity due to the presence of items with awkward shapes.

International relocation experts MoveHub advise that youplan carefully and aim to pack your storage container to around 90% capacity (approx 60 CBM). They advise you to estimate a lower percentage and ensure youallocate extra room to avoid any potential shortage or lack of space. Doing this provides a safety net, guaranteeing that you have sufficient room toaccommodate your belongings without encountering any unexpected constraints.

How many cubic meters does a 20 foot container measure?

A standard 20-foot container has an internal cubic capacity of around 33 cubic meters (1,165 cubic feet), Typically, you can fit around 25-28 cubic meters of goods inside, depending on the size and shape of items. 2

Below are the dimensions of a 20ft container. Again, note that dimensions may vary slightly between companies.

Just as we mentioned with the 40ft container, it's important to remember that although a 20ft container offers around 33 cubic meters (1,165 cubic feet) of space,it is unlikely that you will be able to utilize the full 100% capacity due to irregularly shaped items and the need for proper arrangement. By carefullyplanning your packing strategy, you can aim to fill the 20ft container to around 90% capacity (approx 30 CBM), ensuring efficient utilization of space while leavingsome extra room for any space-consuming objects or unexpected needs.

Once again, the MoveHub website provides excellent advice and tips on loading a 20ft shipping container.

How many cubic meters will my trailer hold?

If you find yourself needing to transport a smaller load using a trailer, don't worry, we've got you covered. Here are some common trailer sizes and estimates of their cubic metercapacities. The capacities are based on a level height of load, so you'll need to adapt them if your load isn't level (a mound of sand or soil, for example).

If you find yourself wondering how heavy your trailer load might be, I can point you to our weight to volume calculator tool, which contains a large list of materials.

I hope you found this calculator and article useful.
