Dimensional weight, also called "dim" weight, is used because the space a packages 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, and use the greater of the two to determine your shipping cost.
 
In the USA and other countries, International and domestic dimensional weights are calculated differently using the formulas below.
 
For International Shipments:
L x W x H (cubic inches) / 166 = Dimensional Weight.
Example: 30" x 24" x 22" = 15,840 / 166 = 96 lbs. (round up to the nearest pound)
 
For Domestic Shipments:
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 Dim weight is given in pounds.

For Ocean shipments, compare Actual Weight in kilograms to Cubic Meters - Charges are based on the greater of the two. 1000 kgs equals 1 Cubic Meter
