## 1. What is CBM?

CBM (abbreviated from Cubic Meter) is a unit of cubic meter, used to measure the volume and size of packages of goods transported by sea and by air. In addition to the actual weight, based on CBM, the carrier will convert from CBM to weight to calculate shipping costs easily or can charge quickly without converting to kg.

Not only can we calculate how much goods to transport in a trip and freight charges when moving goods by plane, passenger car or ship, but CBM helps everyone to arrange the optimal location of goods. The best in the means of transport, helping to carry as much cargo as possible.

## 2. How to calculate standard CBM

Since CBM is in cubic meters, the formula for calculating CBM is calculated according to the width, length, and height of the package. Specifically, the formula is as follows:

CBM = (Width x length x height) x number of packages.

Attention:
– If the packages have different sizes, you apply CBM = (Width x length x height) to each package. Then you put all the packages together to get the total CBM.
– When calculating CBM, you need to pay attention to resize length, height, width in meters.

1CBM = kg? After the calculation is complete, the carrier will convert CBM to kg to calculate the cost of freight, but depending on the shipping method, the conversion method will be different:
– For road: 1CBM = 333kg.
– For air freight: 1CBM = 167kg.
– For seaway: 1CBM = 1000 kg.

## 3. How to calculate CBM for air/road/sea goods

### * How to calculate CBM for air cargo

Air cargo CBM is the unit of cubic meter (m3) applied to packages transported by air. Therefore, according to the above conversion, 1CBM = 167kg. To calculate freight by air, you need to know the volumetric weight of that cargo.

For example: You want to ship the parcel by air with the following information:
– Transport 9 packages, each with a weight of 97kg.
– The size of each piece is 87 x 91 x 98 cm.

To calculate the price, you need to do the following steps:
Step 1: Calculate total weight of goods: The total weight of 9 packages is 873kg.
Step 2: Calculate the volume of the cargo in m3 (CBM)
– The size of a package in cm is 87 x 91 x 98 cm.
– Converting to the size of the parcel in m is 0.87 x 0.91 x 0.98 m.
Therefore, the volume of 9 packages is CBM = (0.87 x 0.91 x 0.98) x 9 packages = 6.9827 m3
Step 3: Convert CBM to weight (kg) of the above 9 packages: 6.9827CBM = 1166 kg.
Step 4: Compare CBM and weight of packages. Whichever has a greater value, you take that value to determine the freight rate.
– CBM = 1166kg.
– Weight = 873kg.
Therefore, the freight calculation will be based on CBM = 1166kg.

### * How to calculate CBM of sea goods

CBM sea freight is used to calculate the freight rate for sea freight. Therefore, when shipping goods by sea, you need to convert 1CBM = 1000kg, thereby calculating sea freight easier.

For example: Shipment by sea includes 7 pieces with the size of each piece is 115 x 96 x 136 cm and the weight of each piece is 766kg.
To calculate the freight rate for this shipment of 7 parcels by sea, you need to calculate according to the following steps:
Step 1: Calculate the total weight of 7 packages: 766 x 7 = 5362kg.
Step 2: Calculate CBM 7 packages.
– The size of each piece in cm is 115 x 96 x 136cm.
– The size of each package in m is 1.15 x 0.96 x 1.36m.
– CBM = (1.15 x 0.96 x 1.36m) x 7 = 10.51m3.
Step 3: Calculate the weight of goods according to CBM: 10.51 x 1000 = 10510kg.
Step 4: Compare CBM and actual weight of packages. If the number is larger, the fee will be charged according to that number. Thus, charge for this sea freight shipment according to CBM.

### * How to calculate CBM of road goods

Road freight CBM is charged for road freight. Weight in CBM is calculated as follows: 1CBM = 333kg.

For example: Calculating freight rates for goods moving by road with dimensions of 113 x 97 x 151 cm and weight of each piece is 965kg.
Calculate the price by following these steps:
Step 1: Calculate the weight of 8 packages 965 x 8 = 7720kg
Step 2: Calculate CBM of 8 pieces.
– Change the size of the parcel to m is 1.13 x 0.97 x 1.51 m.
– Calculate CBM = (1.13 x 0.97 x 1.51) x 8 = 13.240888m3.
Step 3: Convert weight from CBM to road cargo: 13,240888 CBM x 333 = 4409kg.
Step 4: Compare the weight from CBM and the total weight of the package. If you see a lower CBM, then calculate the freight rate by weight.

## 4. How many packages can each container hold?

Arrangement of goods in containers is one of the important factors, deciding whether the cost is optimal or not when transporting. If the goods packed in the container are still not full or lack of space, the transportation costs will increase and cause difficulties in delivery. Therefore, when transporting goods, the carrier in conjunction with the goods manufacturer will calculate the volume of goods when packed into the appropriate container, to avoid excess/lack of space in the container.

Currently, containers have many different types, from 20′ to 40′ containers. Depending on the type of container and the size and volume of the parcel, the calculation of the number of packages on the container is different as follows:
– Number of bales in 20 feet container (volume is 33.2m3): 33.2/bag volume (m3).
– Number of bales in refrigerated 20 feet container (volume is 28.4m3): 28.4/bag volume (m3).
– Number of bales in a regular 40-foot container (volume is 67.6m3): 67.6/bag volume (m3).
– Number of bales in container 40 feet high (volume is 76.3m3): 76.3/Bale volume (m3).
– Number of bales in refrigerated 40 feet container (volume is 67.0m3): 67.0/bale volume (m3).

Inside,bale volume is calculated in (m) with the formula: Length x WIDTH X HEIGHT.

For example Your package has dimensions of length x width x height of 0.3 x 0.24 x 0.6 m, respectively, but if you want to transport it in a 20-foot, 40-foot container, the number of packages needs to be packed to optimize costs. Shipping fee is:
– Volume of bales 0.3 x 0.24 x 0.6 = 0.0432m3.
– The number of packages in a 20-foot container with the above package is 33.2 / 0.0432 = 768 pieces.
– The number of bales in the 40-foot container with the above package is 76.3 / 0.0432 = 1766 bales.
