Dimensional weight

A kilo of feathers does not weigh more than a kilo of led: however it takes up more room on a plane. When transported by air, packages will always be billed according to their dimensional weight. This is due to the limited space available on planes and trucks. Dimensional weight differs from actual weight in that it is calculated according to the dimensions of the package.
For example, the formula for the calculation of a dimensional weight in kilos “kg” is Length(m)*breath(m)*height(m)*167.
The formula for the calculation of dimensional weight in pounds “lbs” is length(in)*breath(in)*height(in)/194.

Example of Dimensional weight in kg :

Take for example a package which is a perfect cube and with a side of 46cm.
Its volume is therefore 0,097 m3 (=46cm*46cm*46cm).
The dimensional weight of this package is .097m3 *167kg = 16.2kg, or 17kg (the weights are always rounded up).
This package will be billed at a volumetric weight of 17kg even if it weights less, or at its real weight if its real weight is more than 17kg.
Following this rules:
If the package weighs 12kg it will be billed at its dimensional weight of 17kg.
If the package actually weighs 25kg it will be billed at 25kg.

Example of Dimensional weight in lbs :

Take for example a package which is a perfect cube and with a side of 18 inches.
Its volume is therefore 5832 inches3.
The dimensional weight of this package is calculated by the formula length (in)*breath (in)*height (in)/194.
Therefore the dimensional weight is 5832/194 = 30.06 lbs
This package will be billed at a dimensional weight of 31 lbs (the weights are always rounded up), even if it weights less, or at its real weight if its real weight is more than 31 lbs.
Following this rules:
If the package weighs 21 lbs it will be billed at its dimensional weight of 31 lbs.
If the package actually weighs 40 lbs it will be billed at 40 lbs.
