Dimensional weight, also called “dim” weight, is used because the space a package takes on an aircraft may cost more than the package’s actual weight. You should calculate dimensional weight on every shipment, compare that to its actual weight the greater of the two will determine your shipping cost. International and domestic dimensional weights are calculated differently using the formulas below.
L x W x H (cubic inches) / 194 = Dimensional Weight.
Example: 30″ x 24″ x 22″ = 15,840 / 194 = 82 lbs.
(round up to the nearest pound)
The Dimweight is given in pounds.
L x W x H (cubic inches) / 166 = Dimensional Weight.
Example: 30″ x 24″ x 22″ = 15,840 / 166 = 95 lbs.
