Dimensional weight is also known as DIM Weight, volumetric weight, Cubed Weight, etc.
Freight carriers utilize the greater of the actual weight or dimensional weight to calculate shipping charges. Dimensional Weight is calculated as (Length x Width x Height) / (Dimensional Factor). Measurements can be made all in inches or all in centimeters, but the appropriate shipping factor must also be used. Different shipping factors are used depending on a shipping mode (i.e. courier shipment or loose airfreight shipment), country criteria and even between different customers.
