Dimensional weight reflects package density, which is the amount of the space a package occupies in relation to its actual weight. Divide the cubic size in inches by 139 to determine dimensional weight in pounds.
Example : ( Length X Width X Height ) / 139 = Dimensional weight in pounds unit.
Actual weight is the package weight rounded up to the next whole pound.
Compare the package actual weight to its dimensional weight. The greater of the two is the billable weight and should be used to calculate the rate. For multiple-package shipments, total the billable weight of all packages in the shipment.
