Commonly used in shipping and freight cubic measurement is calculated as follows and determined some of the fees that are payable.
1. Measure the Dimensions
Measure the length, width, and height of the item ensuring all measurements are in the same unit (e.g., centimeters or meters).
2. Multiply the Dimensions
Use the formula:
=
For example, in meters:
Length = 2 m
Width = 1.5 m
Height = 1 m
3. Convert Units if Needed
For shipping, cubic measurement is often expressed in cubic meters (m³).
If measurements are in centimetres, divide the result by 1,000,000 to convert cm³ to m³:
1. Measure the Package
Measure the length, width, and height of your shipment in centimetres (cm). Make sure to measure the outermost points of the package.
2. Use the Volumetric Weight Formula
Airfreight carriers charge based on the greater of actual weight or volumetric weight. The formula to calculate volumetric weight is:
Dimensional Factor (also called volumetric divisor) is usually 6000 for international air shipments.
Some carriers may use 5000 for smaller cargo or domestic shipments.
3. Example Calculation
Suppose a box measures:
Length = 120 cm
Width = 80 cm
Height = 60 cm
If the actual weight of the package is 70 kg, the airfreight cost will be based on 96 kg, because volumetric weight is higher.
4. Key Points
Always round up to the nearest kg (or carrier’s rule).
Airfreight charges are always based on whichever is higher: actual weight or volumetric weight.
For irregularly shaped or lightweight cargo, volumetric weight often determines the shipping cost.
