Are you in the process of shipping goods and wondering how to calculate the actual weight of your shipment? Specifically, are you trying to determine how many kilograms are in one cubic meter (CBM) of a shipping container?
Understanding this conversion is crucial for exact weight calculations and ensuring the safe transportation of your cargo.
If you're a business owner looking to ship products overseas, knowing this calculation will help. Or, if you're relocating, it will also be useful for the sake of a smooth shipping process. In short, knowing how to calculate your cargo's volumetric weight is beneficial.
In this article, we will find out how to determine the chargeable weight of a shipping container in kilograms for every cubic meter of space it occupies.
We will explore the factors influencing chargeable weight calculations and guide you to meticulously measure your shipment's chargeable weight.
What Is CBM in Shipping?
CBM, or cubic meters, is the standard, internationally-recognized measure of freight volume used in shipping. It is a three-dimensional unit that includes length, width, and height to determine a container's total internal maximum capacity or size.
An accurate measure of CBM helps shippers estimate the cost of their shipment. This prevents the unfortunate situation where an underestimation leads to potential charges from carriers due to insufficient packing materials or inadequate space to place cargo safely.
With CBM used as part of most international shipping contracts initiated by both ocean and air shipping companies, it has become intrinsic in calculating cargo transport costs.
To accurately measure your cargo with CBM, you must take into account not only its overall measurements but also any additional packaging, such as pallets, crates, etc., that may fill up some of the container's space.
Moreover, when using this unit of measurement, be sure to note down every dimension in either metric (meters) or imperial (inches). Once all these details are supplied correctly, a reliable estimate for your cargo transport costs can be determined swiftly and efficiently.
What Does CBM Mean in Shipping?
CBM is an important parameter when shipping air, sea, truck, and van transport due to its relation with the space taken up by freight. Using the CBM unit of measurement, businesses can precisely calculate how much storage space shipments will occupy.
It also allows them to easily estimate storage charges and other associated fees related to the cost of shipping.
CBM stands for "cubic meters" and is calculated by multiplying a shipment's length, width, and height together. This can be done manually or more easily via a specialized software tool that quickly converts all three measurements into total cubic meters.
This enables companies to plan their order volumes efficiently, track how much cargo capacity is available in the shipment, and ensure precise billing when it comes to freight charges.
How many kilograms in a shipping container is 1 CBM?
The answer to this question depends on the type of freight being used. The exchange rate varies with delivery options.
In terms of dimensional weight, 1 CBM represents 167 kg while traveling by air.
On the highway, 1 CBM equals 333 kg. And generally speaking, 1 CBM equals 1000 kg when transporting goods via ship.
How Do I Calculate the CBM of Cargo?
This is a simple calculation. Measure each item's length, width, and height in meters. Then, multiply these numbers to generate a volume. For example, if an item is 2 meters long by 1 meter wide and 1 meter tall, the CBM would be two.
Remember that this formula should be applied for each item individually if they are all different sizes. If multiple identical items are being shipped, it is possible to multiply the CBM figure by the total number of items before adding up the volumes.
By performing calculations like this for each piece of cargo volume, you can quickly identify an exact measurement for your desired shipment as a whole.
Calculating CBM for shipments with irregular shapes
Calculating the cubic meter of a shipment with irregular shapes can be done by obtaining the measurements of the item's longest length, width, and height.
These measurements combined in an equation (length x width x height = CBM) will provide a detailed cubic meter measurement. If the item is cylindrical or round, you will need to measure its radius first, which is half of its diameter.
The formula to calculate CBM for this kind of item involves using three-dimensional geometry and is (πr2h).
Using these equations will ultimately give you an accurate calculation of how much space a shipment with irregular shapes takes up.
Knowing this information is essential to avoid packing too many items into different container types or dealing with oversized shipments that might incur higher transport costs.
Ultimately, this calculation makes planning easier when organizing complex shipment costs, allowing freight forwarders and customers to save both time and money.
How Does CBM Affect Freight Charges?
CBM is a widely used metric for determining the freight charges related to transporting goods. The carriers use CBM-based calculations to create cost estimates.
Depending on the type of transportation being used, each cube meter will convert to a different volumetric weight value in kilograms.
For instance, when using air freight, one cube meter equals 167 kg, while road freight translates to 333 kg per CBM, and ocean freight assigns 1,000 kg per CBM.
The CBM measurements are then used as the basic unit of measure when completing other important calculations for estimating freight charges.
This includes determining loading capacity based on the size of a shipment and comparing it with what can fit on an aircraft or a truck, and calculating cost-effective port-to-port transport for certain routes.
It also means factoring in accessory charges such as pickup/delivery fees or extra de minimis services many cargo companies offer. Plus, it involves finally checking if any clearance customs obstructions are applicable while crossing international borders.
Accordingly, understanding how CBM affects freight charges is critical for anyone involved in business logistics planning and budgeting.
Types of Containers and Their CBM
The standard containers used for the transportation of goods come in three standard models: 20ft, 40ft, and 45ft. Each container model has its own unique size dimensions and CBM rating depending on the type of goods it can contain.
The 20ft container measures 5.898m long, 2.352m wide, and 2.385m tall with a CBM rating of 33.2cbm.
The 40ft container, measuring 12.192m long, 2.352m wide, and 2.385 tall, has a CBM rating of 67cbm.
In comparison, the 45ft container is 13.556m long, 2.378m wide, and 2.412 tall with a 75 CBM rating for effective packaging of consignments of bulkier items that do not fit in a standard-sized container alone.
Furthermore, each container comes with its own specialized fittings, such as shelving systems or specially designed attachments for dry bulk or liquid cargo to ensure they are sealed completely to protect against leaks or spillage during transit time.
This is done while still providing enough air circulation throughout the interior storage chamber due to air vents installed around their rigid walls for convenience in cargo loading and unloading operations in ports located around the world where berth availability.
Conclusion
Understanding the conversion of kilograms to cubic meters is crucial for efficient and cost-effective shipping. Knowing how many kilograms can fit in a shipping container of 1 cubic meter, you can accurately plan and optimize your cargo load.
So, the next time you're shipping goods, remember to calculate the CBM to ensure a smooth and successful transit.
