1. What is a Freight Density Calculator?

Definition: This calculator determines the density of freight in pounds per cubic foot (lb/ft³) based on the shipment's weight and dimensions.

Purpose: It helps shippers and carriers classify freight, determine shipping costs, and ensure proper handling of shipments.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \rho = \frac{W}{L \times W \times H / 1728} \]

Where:

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 Freight Density Calculation

Details: Freight density affects shipping rates, carrier selection, and packaging requirements. Higher density freight typically costs less per pound to ship.

4. Using the Calculator

Tips: Enter the shipment's weight in pounds and all dimensions in inches. Measure to the farthest points including packaging.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1728 used in the formula?
A: There are 1728 cubic inches in a cubic foot (12×12×12), which converts the volume from cubic inches to cubic feet.

Q2: What's considered high density freight?
A: Typically over 15 lb/ft³, though this varies by carrier. High density freight often qualifies for lower rates.

Q3: Should I include packaging in measurements?
A: Yes, always measure the entire shipment including all packaging materials.

Q4: How accurate should my measurements be?
A: Round to the nearest inch for most shipments, but measure precisely for high-value or irregular items.

Q5: Does this work for irregularly shaped items?
A: Yes, but you must measure the maximum length, width, and height of the entire packaged shipment.
