### Cubic Weight Formula:

Total Weight = Length * Width * Height * Weight per cubic unit

### Cubic Weight Definition

Freight transportation companies charge one of two rates for shipping. The first isÂ called dead weight; that is the actual weight of the item to be shipped in its completely boxed and ready-to-ship form.

The other possible weight that a freight company may use to calculate shipping costs is called cubic weight, and that is based on cubic feet/meters. The typical rule of thumb is to charge whichever amount is greater.

To avoid any surprises in invoicing, it is best to calculate shipping weight using a cubic weight calculator. With that information in hand, there are only four simple steps involved in finding out what shipping charges will be:

- Find the dead weight of the package by weighing it
- Use the freight providerâ€™s guidelines to determine the weight per cubic unit.
- Determine which number is greater
- Calculate the shipping charges based on the largest number

Freight carriers will provide the specific weight per cubic unit number to use in the calculation. The designated weight per cubic unit may result in a larger shipping weight overall than the dead weight might. This is what leads to unexpected costs.

Gather five numbers to find the cubic weight. These numbers are:

- Total length
- Total width
- Total height
- Weight per cubic unit
- Dead weight of the shipment

Once you have these numbers, you can easily use the Cubic Weight Calculator to find the cubic weight. Be sure to add the weight of any extra packaging (such as pallets). If the shipment is an irregular shape, take the dimensions from the farthest points; imagine a rectangular box surrounding it and measure accordingly.

In this capacity, the Cubic Weight Calculator is an indispensable tool. It will save the trouble of unexpected expense. It is also fully customizable and available as a widget to place on your site. Any business dealing with shipping freight will find this tool invaluable.
