FedEx, DHL and ECMS calculate their shipping rates using the dimensional weight (volumetric weight) and actual weight (true weight).

Packages that are a large size, but have a low weight, will be measured using dimensional weight. For packages with an actual weight larger than their dimensional weight, the shipping rate will be calculated using the actual weight.

The shipping rate will be based on the heavier of the two weights.

The calculation method for the dimensional weight of a package is as follows:

For FedEx/DHL:

(length x width x height (cm or in))÷ 5,000 (cm) 

For ECMS:

(length x width x height (cm or in))÷ 6,000 (cm) 

DHL offers a volumetric weight calculator tool here.
