How is the density of a handling unit calculated?
To determine the density of a handling unit, first determine the cubage of the handling unit by
multiplying the greatest straight-line dimensions of length, width, and height (depth) in inches, including all projections, if any, as tendered to the carrier for shipment, and dividing the total by 1,728 cubic inches (one cubic foot).
The density is the result of the division of the weight of the handling unit as tendered for shipment by the cubic feet. For instance, the density of a handling unit consisting of boxes unitized on a lift truck pallet measuring 48” x 40” x 45” and weighing 450 pounds is determined as follows: 48” x 40” x 45” = 86,400 cubic inches; 86,400 ÷ 1,728 = 50 cubic feet; 450 lbs. ÷ 50 = 9.00 pounds per cubic foot (pcf).
