Freight class
How to calculate freight density
Multiply the packaged load’s length, width, and height in inches, divide by 1,728 to find cubic feet, then divide total shipping weight in pounds by cubic feet. That yields pounds per cubic foot (PCF).
A quick example
A 500 lb pallet measuring 48 × 40 × 48 inches occupies 53.33 cubic feet. Divide 500 by 53.33: its density is 9.375 PCF.
What to check
- Measure outside length, width, and height in inches.
- Weigh the loaded pallet, including product and packaging.
- Convert cubic inches to cubic feet by dividing by 1,728.
Density is a mathematical property of the packaged shipment. It is not, by itself, a universal freight-class calculator.
