Freight Density Calculator

Calculate total exterior volume and density for identical packed shipping units. This tool stops at physical density and does not assign a freight class.

How the freight density calculator works

Multiply exterior length, width and height in inches and multiply by identical unit count. Divide cubic inches by 1,728 to obtain cubic feet. Total packaged weight is weight per unit times unit count.

Density in pounds per cubic foot is total weight divided by total exterior volume. Metric outputs use exactly 0.45359237 kilograms per pound and 0.028316846592 cubic meters per cubic foot. All dimensions and unit count must be positive; zero weight gives zero density.

Measure the entire shipping envelope, including pallet, overhang and packaging. Density alone does not establish NMFC classification, handling, liability, stowability, carrier charges or safe stacking. Obtain the applicable classification and rating from the carrier or responsible specialist.

Worked example

Two identical units measuring 48 × 40 × 60 inches each occupy 133.3333 cubic feet in total. At 600 pounds per unit, total weight is 1,200 pounds and density is 9 lb/ft³. The same exterior volume is approximately 3.7756 m³.

Sources and assumptions

The source material explains the underlying calculation or pricing structure. Entered prices, costs, schedules and scenario choices are your assumptions; this tool does not obtain supplier quotes or predict actual results.

  • Freight Quote Comparison

    Apply two entered base, per-pallet, fuel and accessorial schedules to the same shipment count.

  • Shipment Cubic Volume

    Convert identical carton dimensions in centimeters to cubic meters and compare with a volume-only usable capacity and space allowance.

  • Pallet Box Capacity

    Count a uniform upright box grid with optional base rotation, total-height and gross-weight limits.

  • Dimensional Shipping Weight

    Calculate a shipment of identical cartons in centimetres and kilograms. Apply your quoted divisor and weight increment to each carton before totaling.
