Dimensional Weight Formula:
From: | To: |
Dimensional weight (also called DIM weight or volumetric weight) is a pricing technique for commercial freight transport which uses an estimated weight calculated from the length, width and height of a package. FedEx and other carriers use this method to account for lightweight packages that take up significant space.
The calculator uses the FedEx Ground dimensional weight formula:
Where:
Explanation: The formula calculates the density-based weight that FedEx uses to determine shipping costs for packages that are lightweight but take up significant space.
Details: Understanding dimensional weight helps businesses accurately estimate shipping costs, optimize packaging to reduce expenses, and avoid unexpected charges from carriers.
Tips: Enter the package dimensions in inches. All values must be valid positive numbers. The calculator will compute the dimensional weight in pounds.
Q1: Why do carriers use dimensional weight?
A: Carriers use dimensional weight to account for the space a package occupies in their vehicles, ensuring they charge appropriately for lightweight but bulky items.
Q2: How is dimensional weight different from actual weight?
A: Actual weight is the physical weight of the package, while dimensional weight is calculated based on package dimensions. Carriers charge based on whichever weight is greater.
Q3: Does the 139 divisor apply to all FedEx services?
A: No, different FedEx services may use different divisors. FedEx Ground uses 139, while FedEx Express services may use different factors.
Q4: How can I reduce dimensional weight charges?
A: Use appropriately sized packaging, compress items when possible, and consider breaking large shipments into multiple smaller packages.
Q5: Are there rounding rules for dimensional weight?
A: Yes, FedEx typically rounds up dimensional weight to the next whole pound for billing purposes.
