The weight of a package using a standard scale rounded to the next full pound.
A 12 1/2 lbs carton will have an "actual weight" of 13 lbs).
Calculation used to reflect a package's density. GPS uses the International Air Transport Association (IATA) volumetric standards (subject to change without notice). This standard is used for all international shipments.
For International Air Express Shipments
Multiply the carton's dimensions and divide the cubic inches by the dimensional weight factor of 139 if measured in inches. If measured in centimeters divide by 5,000 for a dimensional weight in kilos. Divide kilos by 2.20462 to convert to lbs.
A carton with the dimensions of 30"(L) x 20"(W) x 20"(H) = 12,000 cubic inches, divided by 139 = 86.3 pounds for a "dimensional weight" of 87 lbs (always round to the next full pound).
Weight (actual or dimensional - whichever is greater) used in calculating shipping charges. Failure to record the weight of a shipment on the waybill may result in a default weight being applied.
The actual weight of a package is 15 lbs and the dimensional weight is 25 lbs the chargeable weight will be 25 lbs.
Calculation used to determine the three-dimensional space the carton occupies: Length x Width x Height measured in cubic inches or cubic centimeters.
Length or Girth
- Length - is the largest dimension of the carton or object being shipped. For example, if the package is very tall (height is greater than the base) use the height as the length.
- Girth - is the sum of 2 times the width plus 2 times the height or the measurement around the largest area of the cylinder (see illustration).
