1. What is FedEx Volumetric Weight?

Definition: Volumetric weight (also called dimensional weight) is a pricing technique used by shipping companies that calculates the cost based on package volume rather than actual weight.

Purpose: It accounts for the space a package occupies in relation to its actual weight, ensuring fair pricing for lightweight but bulky items.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Length of package (cm or in)
• \( W \) — Width of package (cm or in)
• \( H \) — Height of package (cm or in)
• Dim Factor — Dimensional factor (5000 for kg/cm³, 139 for lb/in³)

Explanation: The package dimensions are multiplied together and divided by the dimensional factor to determine the equivalent volumetric weight.

3. Importance of Volumetric Weight Calculation

Details: Shipping carriers charge based on whichever is greater - the actual weight or volumetric weight. Accurate calculation helps estimate shipping costs and optimize packaging.

4. Using the Calculator

Tips: Enter package dimensions in either centimeters or inches (be consistent). Use 5000 as dimensional factor for kg/cm³ or 139 for lb/in³.

5. Frequently Asked Questions (FAQ)

Q1: Why does FedEx use volumetric weight?
A: To account for lightweight packages that occupy significant space in transport vehicles.

Q2: How do I know whether to use kg or lb?
A: Use the units that match your shipping destination's standard (kg for most countries, lb for US domestic shipments).

Q3: What's the difference between actual and volumetric weight?
A: Actual weight is measured on a scale, while volumetric weight is calculated based on package dimensions.

Q4: When would volumetric weight exceed actual weight?
A: For lightweight, bulky items like pillows, foam, or large boxes with lightweight contents.

Q5: How can I reduce my volumetric weight?
A: Use more compact packaging, compress contents if possible, or break into multiple smaller packages.
