1. What is a Central Transport Density Calculator?

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

Purpose: It helps shippers calculate density which is a key factor in determining freight class and pricing with Central Transport.

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 in³ = 1 ft³) and calculates how much weight occupies each cubic foot.

3. Importance of Density Calculation

Details: Freight carriers like Central Transport use density to determine freight class, which affects shipping rates. Higher density typically means lower freight class and lower costs.

4. Using the Calculator

Tips: Enter the shipment's weight in pounds and dimensions in inches. All values must be > 0. The result shows density in lb/ft³.

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). This converts the volume from cubic inches to cubic feet.

Q2: What's a good density for lower freight classes?
A: Generally, densities above 15 lb/ft³ qualify for better freight classes. The higher the density, the better the class.

Q3: Should I round my density calculation?
A: Central Transport typically uses the actual calculated density to two decimal places for classification.

Q4: How do I measure package dimensions?
A: Measure to the farthest point on each side, including any bulges or protrusions. Round up to the nearest inch.

Q5: Does this work for multiple packages?
A: For multiple identical packages, calculate one then multiply. For different packages, calculate each separately then sum weights and volumes.
