1. What is the XPO Logistics Density Calculator?

Definition: This calculator determines the density of a shipment for freight classification purposes using weight and dimensions.

Purpose: It helps shippers and logistics professionals calculate freight density which is crucial for determining shipping class and costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (pounds per cubic foot)
• \( W \) — Weight (pounds)
• \( L \) — Length (inches)
• \( W \) — Width (inches)
• \( H \) — Height (inches)

Explanation: The formula converts cubic inches to cubic feet (1728 cubic inches = 1 cubic foot) then divides weight by volume to get density.

3. Importance of Density Calculation

Details: Freight density directly impacts shipping costs and class. Higher density items typically qualify for lower freight classes and better rates.

4. Using the Calculator

Tips: Enter the exact weight and dimensions of your shipment. Measure to the nearest inch and weigh to the nearest pound for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1728 used in the formula?
A: 1728 is the number of cubic inches in a cubic foot (12in × 12in × 12in), converting the volume from cubic inches to cubic feet.

Q2: How does density affect freight class?
A: Generally, higher density items qualify for lower (cheaper) freight classes, while lower density items are assigned higher classes.

Q3: Should I round dimensions before calculating?
A: No, use exact measurements. The calculator handles the conversion precisely.

Q4: What's a typical density range for freight?
A: Freight density can range from less than 1 lb/ft³ (very light) to over 50 lb/ft³ (very dense), with most shipments falling between 5-30 lb/ft³.

Q5: Does this include packaging dimensions?
A: Yes, always measure the exterior dimensions of the packaged shipment, including all pallets, crates, or other packaging materials.
