Carton Dimensions
Freight Volume Analysis
A CBM Calculator is an essential logistics tool used to determine the total volume of your shipment in Cubic Meters. Whether you are shipping goods via ocean freight, air freight, or ground transportation, calculating the exact CBM helps you estimate shipping costs, plan cargo space, and determine whether your goods require a full container load (FCL) or less than a container load (LCL).
How is CBM Calculated?
Calculating CBM is straightforward. You simply multiply the length, width, and height of your package together. If your measurements are in centimeters, you must divide the final result by 1,000,000 to convert cubic centimeters into cubic meters. The formula is: Length (m) × Width (m) × Height (m) = CBM.
If you are shipping multiple identical cartons, you calculate the CBM for a single carton and multiply it by the total number of cartons in your shipment to get the overall volume.
How to Use This Calculator
- Select your preferred Unit of Measurement from the dropdown menu (Centimeters, Meters, Millimeters, Inches, or Feet).
- Enter the physical Dimensions of a single carton in the Length, Width, and Height input fields.
- Enter the Total Cartons you plan to ship.
- Enter the Gross Weight per Carton in kilograms. This is optional but highly recommended to calculate volumetric weight.
- Review your results. The main dashboard will instantly display your Total CBM, Cubic Feet (CBF), Volumetric Weight, and Total Gross Weight without requiring any manual conversion.
Frequently Asked Questions
What is Volumetric Weight?
Freight carriers charge based on either the actual gross weight of your shipment or its volumetric weight (dimensional weight), whichever is greater. Volumetric weight is an estimated weight calculated from the volume of the package. In standard air freight, the conversion factor is typically 167 kg per 1 CBM. If you ship a very light but large box, you will be billed for the volumetric weight rather than the actual physical weight.
How many CBM fit in a standard shipping container?
While the exact internal dimensions can vary slightly by manufacturer, a standard 20-foot shipping container can hold approximately 33 CBM of cargo. A standard 40-foot container holds roughly 67 CBM, and a 40-foot High Cube (HC) container can accommodate around 76 CBM of goods. Use these benchmarks to decide if you need an exclusive container.
Can I use inches and feet?
Yes. Our advanced CBM calculator automatically converts imperial measurements (inches and feet) into the metric system. It provides the final output in both Cubic Meters (CBM) and Cubic Feet (CBF), making it compatible with shipping standards in the United States and internationally.
