How is dimensional weight calculated?

Dimensional weight is determined by multiplying a package’s length x height x width (all in centimeters) and divided by 5,000 or such other number as specified by FedEx from time to time on fedex.com. FedEx reserves the right to assess transportation charges based on dimensional weight for all shipments.
