As a business owner or logistics professional, understanding the terminologies used in the shipping industry is essential.
One of these crucial terms is CBM, which stands for Cubic Meter.
It helps to determine the most suitable container size for transporting goods, which can optimize container utilization and reduce transportation costs.
In this guide, we’ll provide you with detailed information on CBM and its significance in the shipping industry.
What Is CBM?
CBM is a shipping term that refers to the volume of cargo or freight that a shipping container can hold.
It is a measurement of the space occupied by the goods inside the container, which is essential for freight forwarders, shipping agents, and logistics companies.
CBM helps these professionals determine the appropriate container size to use for transporting goods and calculating freight charges.
What Does CBM Mean in Shipping?
In the shipping industry, CBM is a critical parameter used to calculate shipping costs.
It helps shippers, carriers, and freight forwarders determine the most suitable container size for transporting cargo.
Shipping rates are often based on a combination of the weight and volume of goods being transported.
CBM is used to calculate the volume of goods being shipped, which is then used to determine the shipping costs.
Why Is CBM Important in Shipping?
CBM is an essential factor in shipping because it helps shippers and logistics professionals determine the right container size to use for transporting cargo.
Shipping containers come in various sizes, including 20 feet, 40 feet, and 45 feet.
By knowing the volume of goods to be shipped, logistics professionals can determine the most suitable container size for the cargo.
This, in turn, helps to optimize container utilization, reducing transportation costs.
How Is CBM Calculated?
CBM is calculated using the dimensions of the cargo in meters.
To calculate the CBM, you need to measure the length, width, and height of the cargo in meters.
Once you have these measurements, multiply the length by the width by the height to get the volume of the cargo in cubic meters.
1. Factors Affecting CBM Calculation
Several factors can affect the accuracy of CBM calculations.
These factors include the shape of the cargo, packing method, unit of measurement used, and margin of error.
The shape of the cargo can affect the accuracy of CBM calculation, especially for irregularly shaped cargo.
2. Benefits of Accurate CBM Calculation
Accurate CBM calculation offers several benefits to shippers, carriers, and logistics professionals.
One of the main benefits is optimized container utilization, which can lead to reduced transportation costs.
Accurate CBM calculation can also lead to accurate shipping rates, improved customer satisfaction, and better inventory management.
3. CBM Calculation Example
Let’s take an example to understand how CBM is calculated.
Suppose you have a consignment that measures 1.5 meters in length, 2 meters in width, and 2 meters in height.
To calculate the CBM of this consignment, you can use the CBM formula:
CBM = Length (m) x Width (m) x Height (m)
Plugging in the measurements for this consignment, we get:
CBM = 1.5 m x 2 m x 2 m
Simplifying the equation, we get:
CBM = 6 cubic meters
Therefore, the CBM of the consignment is 6 cubic meters.
CBM vs. Weight
In shipping, both CBM and weight are essential parameters used to determine shipping costs.
While CBM is a measurement of the volume of cargo, weight is a measurement of the mass of the cargo.
The shipping cost is often calculated based on whichever parameter yields the highest value.
This means that the shipping cost is based on either the CBM or the weight, whichever is greater.
CBM and Container Loading
CBM plays a critical role in container loading.
The objective of container loading is to maximize the use of available space in the container while ensuring that the cargo is adequately secured.
By knowing the CBM of the cargo, logistics professionals can determine the most efficient way to load the container, ensuring that the available space is maximized.
How to Maximize CBM Utilization
To maximize CBM utilization, shippers and logistics professionals should follow the below tips:
Choose the right container size based on the CBM of the cargo: Using a container that is too large or too small can result in inefficiencies and increased transportation costs.
Optimize cargo packaging to minimize unused space: Using packaging that is too large or too small can lead to unused space, which reduces CBM utilization.
Use stackable or collapsible packaging to maximize the use of space: Stackable or collapsible packaging can help maximize space utilization, which improves CBM utilization.
Load the container in a way that maximizes space utilization: By loading the container efficiently, logistics professionals can ensure that the available space is used to its full potential.
Use cargo consolidation to fill any unused space: Consolidating multiple shipments can help fill any unused space in the container, maximizing CBM utilization.
Common Mistakes in CBM Calculation
Some of the common mistakes in CBM calculation include:
Using the wrong unit of measurement: CBM is measured in cubic meters, and using other units can lead to inaccurate calculations.
Measuring the cargo incorrectly: Accurate measurements are crucial for CBM calculation, and any errors can result in inaccurate calculations.
Failing to account for the shape of the cargo: The shape of the cargo can impact the accuracy of CBM calculations, especially for irregularly shaped cargo.
Failing to consider the margin of error: There is always a margin of error when measuring cargo, and failing to account for it can result in inaccurate CBM calculations.
CBM is a crucial factor in shipping that helps shippers and logistics professionals determine the most suitable container size for transporting goods.
Accurate CBM calculation can lead to optimized container utilization, reduced transportation costs, and improved efficiency.
By following the tips outlined in this guide, shippers and logistics professionals can maximize CBM utilization and improve their shipping operations.

1. What is the difference between CBM and volume?
CBM is a measurement of the space occupied by the cargo in a container, while volume is a measurement of the total space available in the container.
2. How is the CBM of irregularly shaped cargo calculated?
The CBM of irregularly shaped cargo is calculated by dividing it into smaller rectangular shapes and calculating the CBM of each section.
3. Is it better to use a larger or smaller container for shipping?
It is better to use a container that is just the right size for your cargo.
Using a larger container than necessary will result in wasted space and increased transportation costs, while using a smaller container can lead to damage to the cargo and additional expenses.
4. How can accurate CBM calculation benefit my business?
Accurate CBM calculation can benefit your business in several ways, including optimized container utilization, reduced transportation costs, improved customer satisfaction, and better inventory management.
5. What is the difference between CBM and weight-based pricing?
CBM-based pricing calculates shipping costs based on the volume of the cargo being shipped, while weight-based pricing calculates shipping costs based on the weight of the cargo being shipped.
