Glossar CBM
Brief description of the term
CBM stands for "cubic metre" and is a unit of measurement that indicates the volume of an object.
In the area of logistics and shipping CBM often used to calculate the space required for a shipment and to determine the associated shipping costs.
This figure is particularly relevant when it comes to transporting goods that are large and bulky but relatively light.
What is CBM? Detailed explanation
Importance of the unit of measurement in logistics
CBM is a key performance indicator in international shipping and plays an important role in the planning and pricing of freight transport.
It helps logistics companies to make efficient use of the space available in containers, lorries or aircraft and to calculate costs accordingly.
A precise understanding and accurate calculation of CBM are therefore essential for optimising the supply chain.
The key figure is particularly important as it influences not only the volume, but also the freight class and the chargeable weight.
What is CBM? Calculation of the key figure
The key figure is calculated by multiplying the dimensions of the package: length, width and height, each in metres.
For example, a box measuring 2 metres in length, 2 metres in width and 2 metres in height has a volume of 8 CBM (2 m x 2 m x 2 m = 8 m³).
If you send several parcels, the calculation is carried out for each parcel and the volumes are added together.
For irregularly shaped packages or bulky objects, there are special formulas to calculate the volume, such as for cylindrical objects, where the formula (π × r^2 × h) is used.
Application of the key figure in shipping
CBM is decisive for the calculation of shipping costs. For large but lightweight consignments, the Volumetric weight used.
The Volumetric weight is calculated by adding the CBM of the consignment is converted into a weight - normally using a fixed conversion factor.
This ensures that both the volume and the actual weight of the consignment are taken into account when calculating the price.
This method prevents very light but bulky goods from being shipped disproportionately cheaply.
CBM and freight types
The meaning varies depending on the type of transport:
- Ocean FreightThe unit of measurement used to calculate the space inside a container. Freight costs are often calculated based on volume, especially for LCL (Less than Container Load) shipments.
- Air Freight: For air freight, the Volumetric weight often more important than the actual weight, as the limited space must be utilised efficiently.
- RoadFor road and rail freight, the unit of measurement is also used to determine space requirements and costs. A conversion factor is often used here, which can vary depending on the carrier.
Practical tips on the use of CBM
In practice, it is helpful to use onlineCBM-calculators and apps to simplify the calculation. These tools make it possible to easily convert various units into CBM and to determine the volume precisely.
When planning consignments, especially for international transport, a precise calculation ensures transparent and fair pricing.
Economy and efficiency
The precise calculation of CBM companies can significantly improve the cost-effectiveness and efficiency of their supply chains. Precise calculation enables optimum utilisation of transport capacities and prevents unnecessary costs due to inefficient use of space.
FAQs
- How does it influence CBM the shipping costs?
It affects the shipping costs, as many carriers calculate their prices based on volume, especially for large but light shipments. A higher CBM means that the consignment takes up more space and therefore incurs higher costs. The Volumetric weight is often used to ensure that the available space is utilised efficiently. - Can I CBM with standard online tools?
Yes, there are numerous online calculators and apps to help you calculate the CBM of your consignment. These tools make it easier to convert dimensions and give you an accurate idea of the volume of your shipment. They are particularly useful for planning and calculating shipping costs, as they save time and ensure accuracy. - What is the difference between CBM and Volumetric weight?
CBM (cubic metre) measures the volume of a consignment, while the Volumetric weight is a method of converting this volume into a weight. The Volumetric weight is used to calculate the shipping costs for bulky but lightweight goods more fairly. It ensures that the price takes into account both the volume and the actual weight of the shipment. - Why is CBM particularly important for air freight?
With air freight, the available space is often limited, which is why the Volumetric weight plays a decisive role. Large but lightweight packages take up a lot of space, which is why CBM and the resulting Volumetric weight are decisive for the pricing. This ensures a fair distribution of costs based on space requirements.
