What is CBM, and how is it calculated?
CBM stands for Cubic Metre, a unit of measurement used in shipping and logistics. It shows how much room your cargo takes. CBM is calculated by multiplying length, width, and height (in meters). For metric, first change sizes to meters (100cm = 1m), then multiply. For inches, the calculator first calculates cubic inches (L × W × H), then divides by 61,023.744 to convert to cubic meters. For cubic feet, multiply CBM by 35.3147. For example, a box that is 100cm × 50cm × 50cm is 1m × 0.5m × 0.5m, which equals 0.25 CBM.
How are volumetric weights calculated?
The ways for determining volumetric weight vary by shipping type, but all methods use length, width, and height in centimetres. Express/courier services (such as DHL, FedEx, UPS) use a volume calculation of (L × W × H) divided by 5,000. Air freight is divided by 6,000, ocean freight by 1,000, and rail freight by 3,000. These turn your package size into a "weight" for prices. Shipping companies charge by whichever weight is higher: the actual weight or the volumetric weight. This keeps large but lightweight items from costing too much to ship.
How is container capacity calculated?
To determine how many packages fit in a container, divide the container's volume by the volume of each package. If a 20ft container holds 33 CBM and your package is 0.25 CBM, you can fit 33 ÷ 0.25 = 132 packages. This is the best-case number if everything fits perfectly. In real life, count on 60-80% of that total, because of wasted space and how items are packed. Experts can load up to 80%; mixed cargo usually fits about 60-70%.
