Shipping costs have historically been calculated on the basis of gross weight such as kilograms. By charging only by weight, lightweight, low density packages become unprofitable for freight carriers due to the amount of space they take up in the truck/aircraft/ship in proportion to their actual weight. The concept of Cubic Weight has been adopted by the transport industry worldwide as a uniform means of establishing a minimum charge for the cubic space a package occupies.

You can use our Cubic Weight Calculator to determine the chargeable weight of your package.
