# Volumetric (Dimensional) Weight

Volumetric (Dimensional) Weight is a transportation industry term referring to the density of cargo or a package, which determines how the shipment will be billed: according to its actual weight, or to its cubic volume (that is, the space it occupies on an aircraft or vehicle).

## The Formulas

### For INTERNATIONAL EXPRESS shipments (CWB):

To determine the cubic volume in pounds (lbs), measure the three dimensions of your shipment in inches and multiple them together (height x length x width). Then divide this product by the number 139. That is the volumetric weight.

To calculate in kilograms (kgs) instead, measure in centimeters and divide the product (or “cm3”) by 5,000.

### For INTERNATIONAL CARGO shipments (HAWB):

To determine the cubic volume in pounds (lbs), measure the three dimensions of your shipment in inches and multiple them together (height x length x width). Then divide this product by the number 166. That is the volumetric weight.

To calculate in kilograms (kgs) instead, measure in centimeters and divide the product (or “cm3”) by 6,000.

### For DOMESTIC shipments:

Divide the cubic volume in inches by the number 139 for the volumetric weight in pounds (lbs).

Shippers generally will be charged the greater of the two assessed weight values: Actual or Volumetric
