Density formula

Density is weight divided by cubic volume.

Freight density describes how much weight is packed into a unit of space. In U.S. freight work it is often expressed as pounds per cubic foot. Metric operations may use kilograms per cubic meter.

density = total shipment weight ÷ total shipment volume

If you only have carton dimensions, use the CBM calculator first to determine total cubic volume, then return here with the shipment weight.
