Cubic Weight

Your freight may be cubed while in our possession and if the Cubic Weight is larger then the weight, the cubic weight will be used to calculate your freight charges. If you'd like the most accurate rate then calculate your cubic weight, if it's larger then the weight enter it in the weight field.

Below is how Cubic Weight is calculated, for those that are interested. Or you can simply use the Cube Calculator on the New Order page.

The cubic weight is based on the cubic feet of a shipment. For each cubic foot the cubic weight is 10 lbs. To calculate the cube you need to have the dimensions of your freight in inches.

Multiply the dimensions for each package then divide that amount by 1728 to get the cubic feet. Multiply the cubic feet by 10 to get the cubic weight (lbs).

For an example we are going to use the following shipment:

Here is how you would calculate each skid.

In this example the cubic weight is more then the weight. So if you wanted the most accurate freight rate enter 1511 in the Weight field on the New Orders page. That way there are no surprises at the time of invoicing.

Also we recommend you enter the dimensions in the comments field. This way you know you cubed your freight and we don’t end up re-cubing you freight which may be an inch or two off of your dimensions.

If you are asking why use 1728? What does this number represent? Here is a quick explanation for you.

1728 is the amount of cubic inches within in one cubic foot.

A foot contains 12” so if you calculate the cube of 12”x12”x12” it equals 1728 cubic inches.

In the example above if you were just to multiply 48” x 40” x 64” you would get 122880 cubic inches.

So by dividing 1228800 by 1728 you get the amount of cubic feet (71.1).
