What’s the difference between actual and dimensional weight?

Actual weight is the weight of a package on a scale. Dimensional weight is related to the package’s measurements and the space it occupies in the aircraft while being transported. Airlines take into consideration the greater value between actual and dimensional weight when applying rates. Because of this Ship7 applies the same rule to packages. The following formula is used:
Length x Width X Height (in inches) / 139 or Length x Width X Height (in centimeters) / 5000
