What is the formula for Volumetric Weight?

Volumetric weight, or dimensional weight, is the method of determining the "weight" of a volume of space that is occupied by matter. Therefore, the dimensions of a package, its length, width, and height, are used to determine the weight of the package relative to the volume it occupies.

It is computed as follows:

Length (inches) x Width (inches) x Height (inches) of the item in its original packaging / 166 (dimensional weight factor)

Please note that we follow the dimensional weight factor of the International Air Weight Transport Association (IATA).
