How to Calculate CBM for Ocean Freight? | Latest Version 2020 With Example

To ocean freight your packages when importing from China, you need to be familiar with the concept of CBM. Knowing Cubic Meter or CBM is necessary for calculating the freight cost. In this article by ddpch, read all about how to calculate CBM for ocean freight.

What is CBM?

Before reading about how to calculate CBM for ocean freight, let us see what is CBM and what it stands for. CBM, or cubic meter, is simply the shipment volume. The volume is then used for other important international freight measurements (courier, ocean or sea freight) including:

Dimensional weight (CBM to kg or CFT to lbs)-Dimensional weight is a way of generating a theoretical amount of bulky but compact shipments.

Chargeable weight – Chargeable weight is merely the greater weight or weight of the dimension (aka size). In other words, ocean freight pricing is relatively averse to weight and more size-focused, because the dimensional weight typically plays a more important role than the actual mass.

Freight class – Most LTL trucking carriers have also produced a theoretical number to reimburse truckers for overweight shipping loads. Most truck-shipped goods go through weight-determined, clear freight class categories. But CBM can also play a major role in determining the class of freight.

How to Calculate CBM for Ocean Freight?

The CBM formula is a simple procedure. It is the sum of quantities of the length, width, and height items. If your shipment has numerous products of different dimensions, simply repeat the formula for each dimension and add the volumes.

To calculate the CBM for ocean freight, you must easily follow the below steps:

  1. Select Measurement Unit (metric or imperial) 
  2. Input the number of units (pallets, boxes, or crates) and then the length, width, and height of the unit. 
  3. Then the total volume will be shown inline.

If you want to measure the CBM of cylindrical packages, check with the carrier if they square the circle (the diameter will be converted to width and height). Or you can use your basic mathematic skills and multiply the package size by Pi and then again by 2 (πr2). Then multiply that result by packet length to get the volume.

Example of CBM for Ocean Freight

Now that we read all about how to calculate CBM  for ocean freight, let us look into one example:

If the length, height, and width of the shipping cargo are respectively 2.3 meters, 1.4 meters, and 2 meters, the volume of cargo is 2.3 X 1.4 X 2.00 = 6.44 CBM.

In case you have the measurement in inches or centimeters, you need to convert to meters first, and then calculate CBM, which is simpler for you. If freight forwarder quotes a rate of USD 10.00 per CBM, the rate is USD 6.44 per CBM X 10.00 = USD 64.40.
